PERL – a Register-Less Processor
PERL { A Register-Less Processor A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by P. Suresh to the Department of Computer Science & Engineering Indian Institute of Technology, Kanpur February, 2004 Certificate Certified that the work contained in the thesis entitled \PERL { A Register-Less Processor", by Mr.P. Suresh, has been carried out under my supervision and that this work has not been submitted elsewhere for a degree. (Dr. Rajat Moona) Professor, Department of Computer Science & Engineering, Indian Institute of Technology, Kanpur. February, 2004 ii Synopsis Computer architecture designs are influenced historically by three factors: market (users), software and hardware methods, and technology. Advances in fabrication technology are the most dominant factor among them. The performance of a proces- sor is defined by a judicious blend of processor architecture, efficient compiler tech- nology, and effective VLSI implementation. The choices for each of these strongly depend on the technology available for the others. Significant gains in the perfor- mance of processors are made due to the ever-improving fabrication technology that made it possible to incorporate architectural novelties such as pipelining, multiple instruction issue, on-chip caches, registers, branch prediction, etc. To supplement these architectural novelties, suitable compiler techniques extract performance by instruction scheduling, code and data placement and other optimizations. The performance of a computer system is directly related to the time it takes to execute programs, usually known as execution time. The expression for execution time (T), is expressed as a product of the number of instructions executed (N), the average number of machine cycles needed to execute one instruction (Cycles Per Instruction or CPI), and the clock cycle time (), as given in equation 1. -

Programmable Digital Microcircuits - a Survey with Examples of Use
- 237 - PROGRAMMABLE DIGITAL MICROCIRCUITS - A SURVEY WITH EXAMPLES OF USE C. Verkerk CERN, Geneva, Switzerland 1. Introduction For most readers the title of these lecture notes will evoke microprocessors. The fixed instruction set microprocessors are however not the only programmable digital mi• crocircuits and, although a number of pages will be dedicated to them, the aim of these notes is also to draw attention to other useful microcircuits. A complete survey of programmable circuits would fill several books and a selection had therefore to be made. The choice has rather been to treat a variety of devices than to give an in- depth treatment of a particular circuit. The selected devices have all found useful ap• plications in high-energy physics, or hold promise for future use. The microprocessor is very young : just over eleven years. An advertisement, an• nouncing a new era of integrated electronics, and which appeared in the November 15, 1971 issue of Electronics News, is generally considered its birth-certificate. The adver• tisement was for the Intel 4004 and its three support chips. The history leading to this announcement merits to be recalled. Intel, then a very young company, was working on the design of a chip-set for a high-performance calculator, for and in collaboration with a Japanese firm, Busicom. One of the Intel engineers found the Busicom design of 9 different chips too complicated and tried to find a more general and programmable solu• tion. His design, the 4004 microprocessor, was finally adapted by Busicom, and after further négociation, Intel acquired marketing rights for its new invention. -

ABSTRACT Virtualizing Register Context
ABSTRACT Virtualizing Register Context by David W. Oehmke Chair: Trevor N. Mudge A processor designer may wish for an implementation to support multiple reg- ister contexts for several reasons: to support multithreading, to reduce context switch overhead, or to reduce procedure call/return overhead by using register windows. Conventional designs require that each active context be present in its entirety, increasing the size of the register file. Unfortunately, larger register files are inherently slower to access and may lead to a slower cycle time or additional cycles of register access latency, either of which reduces overall performance. We seek to bypass the trade-off between multiple context support and register file size by mapping registers to memory, thereby decoupling the logical register requirements of active contexts from the contents of the physical register file. Just as caches and virtual memory allow a processor to give the illusion of numerous multi-gigabyte address spaces with an average access time approach- ing that of several kilobytes of SRAM, we propose an architecture that gives the illusion of numerous active contexts with an average access time approaching that of a single active context using a conventionally sized register file. This dis- sertation introduces the virtual context architecture, a new architecture that virtual- izes logical register contexts. Complete contexts, whether activation records or threads, are kept in memory and are no longer required to reside in their entirety in the physical register file. Instead, the physical register file is treated as a cache of the much larger memory-mapped logical register space. The implementation modifies the rename stage of the pipeline to trigger the movement of register val- ues between the physical register file and the data cache. -
