The Design and Verification of the Alphastation 600 5-Series Workstation by John H
The Design and Verification of the AlphaStation 600 5-series Workstation by John H. Zurawski, John E. Murray, and Paul J. Lemmon ABSTRACT The AlphaStation 600 5-series workstation is a high-performance, uniprocessor design based on the Alpha 21164 microprocessor and on the PCI bus. Six CMOS ASICs provide high-bandwidth, low-latency interconnects between the CPU, the main memory, and the I/O subsystem. The verification effort used directed, pseudorandom testing on a VERILOG software model. A hardware-based verification technique provided a test throughput that resulted in a significant improvement over software tests. This technique currently involves the use of graphics cards to emulate generic DMA devices. A PCI hardware demon is under development to further enhance the capability of the hardware-based verification. INTRODUCTION The high-performance AlphaStation 600 5-series workstation is based on the fastest Alpha microprocessor to date -- the Alpha 21164.[1] The I/O subsystem uses the 64-bit version of the Peripheral Component Interconnect (PCI) and the Extended Industry Standard Architecture (EISA) bus. The AlphaStation 600 supports three operating systems: Digital UNIX (formerly DEC OSF/1), OpenVMS, and Microsoft's Windows NT. This workstation series uses the DECchip 21171 chip set designed and built by Digital. These chips provide high-bandwidth, low-latency interconnects between the CPU, the main memory, and the PCI bus. This paper describes the architecture and features of the AlphaStation 600 5-series workstation and the DECchip 21171 chip set. The system overview is first presented, followed by a detailed discussion of the chip set. The paper then describes the cache and memory designs, detailing how the memory design evolved from the workstation's requirements. -

On the Cognitive Prerequisites of Learning Computer Programming
On the Cognitive Prerequisites of Learning Computer Programming Roy D. Pea D. Midian Kurland Technical Report No. 18 ON THE COGNITIVE PREREQUISITES OF LEARNING COMPUTER PROGRAMMING* Roy D. Pea and D. Midian Kurland Introduction Training in computer literacy of some form, much of which will consist of training in computer programming, is likely to involve $3 billion of the $14 billion to be spent on personal computers by 1986 (Harmon, 1983). Who will do the training? "hardware and software manu- facturers, management consultants, -retailers, independent computer instruction centers, corporations' in-house training programs, public and private schools and universities, and a variety of consultants1' (ibid.,- p. 27). To date, very little is known about what one needs to know in order to learn to program, and the ways in which edu- cators might provide optimal learning conditions. The ultimate suc- cess of these vast training programs in programming--especially toward the goal of providing a basic computer programming compe- tency for all individuals--will depend to a great degree on an ade- quate understanding of the developmental psychology of programming skills, a field currently in its infancy. In the absence of such a theory, training will continue, guided--or to express it more aptly, misguided--by the tacit Volk theories1' of programming development that until now have served as the underpinnings of programming instruction. Our paper begins to explore the complex agenda of issues, promise, and problems that building a developmental science of programming entails. Microcomputer Use in Schools The National Center for Education Statistics has recently released figures revealing that the use of micros in schools tripled from Fall 1980 to Spring 1983. -

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements. -
