The W o r k s h o p was o r i g i n a l l y p l a n n e d to last two full days, but later e x p a n d e d to more than three when i n c l u d i n g the Sunday afternoon Basic T u t o r i a l on M i c r o p r o g r a m m i n g . On M o n d a y morning, S e p t e m b e r 30, 1974, an Adv a n c e d T u t o r i a l followed b e f o r e the actual W o r K s h o p began.

It is p l a n n e d to take place in the B o s t o n area d u r i n g S e p t e m b e r 1975. Highlights Tne ever w i d e n i n g i n t e r e s t into the field of m i c r o p r o g r a m m i n g could r e a l l y be felt d u r i n g the well done t u t o r i a l sessions. It was f u r t h e r m o r e d e m o n s t r a t e d by the session themes. The P r o g r a m C o m m i t t e e should be cong r a t u l a t e d for its choice. There were basically four sessions on M i c r o p r o g r a m m i n g Architecture, two on P e r f o r m a n c e ~vulation, two on Emulation, and at least three on M i c r o p r o g r a m m i n g L a n g u a g e aspects. O p t i m i z a t i o ~ R e a l i b i l i t ~ and T e a c h i n g were the o t n e r focal points. But M i c r o p r o c e s s o r s , Microprogrammable Minicomputers, Input/Output and O p e r a t i n g S y s t e m s w e r e also covered. One session was, in p a r t i c u l a r , i n t e r e s t i n g for a E u r o p e a n attendent.

Other E u r o p e a n c o n t r i b u t i o n s w e r e p r e s e n t e d at regular sessions. A u t h o r s included G.F. Coulouris, et al., of Queen Mary College, U n i v e r s i t y of London, F. Dromard, Institut de Programmation, U n i v e r s i t ~ de Paris IV, H. Berndt as well as W. Rottmann of Siemens in Munich, and J.P. S c h o e l l k o p f of ENSIMAG. It was a g r a t i f y i n g e x p e r i e n c e to e n c o u n t e r such a strong r e p r e s e n t a t i o n of the European s c i e n t i f i c c o m m u n i t y at a s p e c i l i z e d A m e r i c a n conference. There appeared even more E u r o p e a n s in a t t e n d e n c e than Canadians. The obvious c o n c l u s i o n is c e r t a i n l y not that E u r o p e a n s are more a f f l u e n t at times of e c o n o m i c crises, but that there exists a real need for i n t e r n a t i o n a l rec o g n i t i o n as well as e x c h a n g e of ideas among E u r o p e a n scientists in the :~icroprog r a m m i n g field. The other h i g h l i g h t s were purely scientific I.

Other focal points seemed to be Mic r o p r o g r a m O p t i m i z a t i o n (6 papers) and E m u l a t i o n w h e r e the CDC 5600 series of processors r e c e i v e d p a r t i c u l a r attention. (J. W i l k o r d e s c r i b i n g the M P - 6 0 system and R. M a t t s o n and A.B.

But other p a p e r s (by Louise Jones of du Pont and D.M. W y c k o f f of C a l i f o r n i a State Univ e r s i t y at Sacramento) proved e q u a l l y stimulating. Most impressive was p r o b a b l y the session M i c r o p r o g r a m A r c h i t e c t u r e II, subtitle An Emulation Laboratory, where the design of the E ~ Y c o m p u t e r was presented. This session was aptly c h a i r e d by Michael Flynn of then John H o p k i n s U n i v e r s i t y and Palyn A s s o c i a t e s at San Jose. In the Teaching area (panel discussion) there a p p e a r e d just as m u c h a g r e e m e n t that m i e r o p r o g r a m m i n g should be included in c o m p u t e r science curriculums, as c o m p l a i n t that m a n u f a c t u r e s are r e l u c t a n t to p r o v i d e m i c r o p r o g r a m m i n g tools.

The co-chairmen will be Professor Michael Flynn of Stanford University and Professor Oscar Garcia of the University of South Florida. The first day, January 19, will be devoted to a tutorial on a topic of current interest. As you recall our tutorial on Microcomputer Structure held at this year's symposium was extremely popular and well received. The Symposium on Computer Architecture is the only forum whose central theme is the theory and practice of computer and digital system organization. Topics covered include: Hardware/Firmware/Software Architectural Interactions Microcomputer System Architecture I/O Architecture Maxicomputers Multiprocessors Distributed Function Architectures Computer Networks High Level Language Machines Measurement and Performance Evaluation Design Automation of Digital Systems Description, Analysis, Synthesis, and Simulation Tools Special Purpose Architectures Computer Structures Education We are particularly interested in receiving papers from European authors relating to proposed or existing systems. Potential authors should be encouraged to confrom to the paper format established by previous Computer Architecture symposia and described in the booklet, "Information for IEEE Authors," available from the IEEE Editorial Department, 345 East 47th Street, New York, New York, 10017. That is, the papers should have an abstract, an introduction and survey of previous related work, their results, and conclusions. References to easily obtainable papers are also desirable.

The microcomputer is ushering in new and e x c i t i n g e l e c t r o n i c system design p o s s i b i l i t i e s .
Following the w i l d f i r e success of the f i r s t
generation
of microprocessors, many semiconductor manufacturers are now developing increasingly sophisticated computers in extremely small packages - the day of the powerful "processor on a chip" has arrived~ This three day course being held for s c i e n t i s t s , engineers and managers by the Polytechnic of Central London at the Congress Palace in Florence, Italy -
n association with Florence University's Faculty of Engineering -
presents a thorough i n t r o d u c t i o n to the explosive technology of microcomputers and t h e i r applications. There is p a r t i c u l a r emphasis on bringing the a t t r i b u t e s of microprocessors and f u l l
microcomputer systems into perspective, from
both technical and economic standpoints, r e l a t i v e to hard-wired logic systems on the one hand, and the larger-scale minicomputer systems, on the other. The course begins with an introduction to microprocessor devices and microcomputer systems. Since device a v a i l a b i l i t y
is a prime consideration in
newly-emerging technology areas, a very extensive and d e f i n i t i v e two-part s~rvey of the microprocessors currently in commercial production is then

presented. Next the closely inter-related matters of hardware and software features are treated. Technical and non-technical factors to be considered in the overall design and implementation of microcomputer systems are given, followed by a sequence of several case studies of systems previously developed for applications ranging from data communications to "microperipherals". On the final day of the course a forum focussing on the anticipated value of microcomputers to industry is held which, in conjunction with two workshop sessions during the course, provides for l i v e l y discussion of the course content.

It was f u r t h e r m o r e d e m o n s t r a t e d by the session themes. The P r o g r a m C o m m i t t e e should be cong r a t u l a t e d for its choice. There were basically four sessions on M i c r o p r o g r a m m i n g Architecture, two on P e r f o r m a n c e ~vulation, two on Emulation, and at least three on M i c r o p r o g r a m m i n g L a n g u a g e aspects. O p t i m i z a t i o ~ R e a l i b i l i t ~ and T e a c h i n g were the o t n e r focal points. But M i c r o p r o c e s s o r s , Microprogrammable Minicomputers, Input/Output and O p e r a t i n g S y s t e m s w e r e also covered.

There appeared even more E u r o p e a n s in a t t e n d e n c e than Canadians. The obvious c o n c l u s i o n is c e r t a i n l y not that E u r o p e a n s are more a f f l u e n t at times of e c o n o m i c crises, but that there exists a real need for i n t e r n a t i o n a l rec o g n i t i o n as well as e x c h a n g e of ideas among E u r o p e a n scientists in the :~icroprog r a m m i n g field.

But other p a p e r s (by Louise Jones of du Pont and D.M. W y c k o f f of C a l i f o r n i a State Univ e r s i t y at Sacramento) proved e q u a l l y stimulating.

Zaks Universite de Complegne B.P. 233 60206 CompiSgne, France Dear Rodnay: I am writing to inform you of our plans for the Third Annual Symposium on Computer Architecture to be held on January ]9-21, 1976 at the Fort Harrison Jack Tar Hotel in Clearwater, Florida. The co-chairmen will be Professor Michael Flynn of Stanford University and Professor Oscar Garcia of the University of South Florida. The first day, January 19, will be devoted to a tutorial on a topic of current interest. As you recall our tutorial on Microcomputer Structure held at this year's symposium was extremely popular and well received. The Symposium on Computer Architecture is the only forum whose central theme is the theory and practice of computer and digital system organization. Topics covered include: Hardware/Firmware/Software Architectural Interactions Microcomputer System Architecture I/O Architecture Maxicomputers Multiprocessors Distributed Function Architectures Computer Networks High Level Language Machines Measurement and Performance Evaluation Design Automation of Digital Systems Description, Analysis, Synthesis, and Simulation Tools Special Purpose Architectures Computer Structures Education We are particularly interested in receiving papers from European authors relating to proposed or existing systems. Potential authors should be encouraged to confrom to the paper format established by previous Computer Architecture symposia and described in the booklet, "Information for IEEE Authors," available from the IEEE Editorial Department, 345 East 47th Street, New York, New York, 10017. That is, the papers should have an abstract, an introduction and survey of previous related work, their results, and conclusions. References to easily obtainable papers are also desirable.

The microcomputer is ushering in new and e x c i t i n g e l e c t r o n i c system design p o s s i b i l i t i e s .
Following the w i l d f i r e success of the f i r s t
generation
of microprocessors, many semiconductor manufacturers are now developing increasingly sophisticated computers in extremely small packages - the day of the powerful "processor on a chip" has arrived~ This three day course being held for s c i e n t i s t s , engineers and managers by the Polytechnic of Central London at the Congress Palace in Florence, Italy -
n association with Florence University's Faculty of Engineering -
presents a thorough i n t r o d u c t i o n to the explosive technology of microcomputers and t h e i r applications. There is p a r t i c u l a r emphasis on bringing the a t t r i b u t e s of microprocessors and f u l l
microcomputer systems into perspective, from
both technical and economic standpoints, r e l a t i v e to hard-wired logic systems on the one hand, and the larger-scale minicomputer systems, on the other. The course begins with an introduction to microprocessor devices and microcomputer systems. Since device a v a i l a b i l i t y
is a prime consideration in
newly-emerging technology areas, a very extensive and d e f i n i t i v e two-part s~rvey of the microprocessors currently in commercial production is then

presented. Next the closely inter-related matters of hardware and software features are treated. Technical and non-technical factors to be considered in the overall design and implementation of microcomputer systems are given, followed by a sequence of several case studies of systems previously developed for applications ranging from data communications to "microperipherals". On the final day of the course a forum focussing on the anticipated value of microcomputers to industry is held which, in conjunction with two workshop sessions during the course, provides for l i v e l y discussion of the course content.
