SPIM S20: a MIPS R2000 Simulator∗
SPIM S20: A MIPS R2000 Simulator∗ 1 th “ 25 the performance at none of the cost” James R. Larus [email protected] Computer Sciences Department University of Wisconsin–Madison 1210 West Dayton Street Madison, WI 53706, USA 608-262-9519 Copyright °c 1990–1997 by James R. Larus (This document may be copied without royalties, so long as this copyright notice remains on it.) 1 SPIM SPIM S20 is a simulator that runs programs for the MIPS R2000/R3000 RISC computers.1 SPIM can read and immediately execute files containing assembly language. SPIM is a self- contained system for running these programs and contains a debugger and interface to a few operating system services. The architecture of the MIPS computers is simple and regular, which makes it easy to learn and understand. The processor contains 32 general-purpose 32-bit registers and a well-designed instruction set that make it a propitious target for generating code in a compiler. However, the obvious question is: why use a simulator when many people have workstations that contain a hardware, and hence significantly faster, implementation of this computer? One reason is that these workstations are not generally available. Another reason is that these ma- chine will not persist for many years because of the rapid progress leading to new and faster computers. Unfortunately, the trend is to make computers faster by executing several instruc- tions concurrently, which makes their architecture more difficult to understand and program. The MIPS architecture may be the epitome of a simple, clean RISC machine. In addition, simulators can provide a better environment for low-level programming than an actual machine because they can detect more errors and provide more features than an actual computer. -

Microprocessors have become a part of our daily lives and it would be difficult to imagine life without them today. From digital wrist watches, to pocket calculators, from microwaves, to cars, toys, security systems, navigation, to credit cards, microprocessors are ubiquitous. All this has been made possible by remarkable developments in semiconductor technology enabling in the last 30 years, enabling the implementation of ideas that were previously beyond the average computer architect’s grasp. In this paper, we discuss the various microprocessor technologies, starting with a brief history of computing. This is followed by an in-depth look at processor architecture, design philosophies, current design trends, RISC processors and CISC processors. Finally we discuss trends and directions in microprocessor design. Brief Historical Overview Mechanical Computers A French engineer by the name of Blaise Pascal built the first working mechanical computer. This device was made completely from gears and was operated using hand cranks. This machine was capable of simple addition and subtraction, but a few years later, a German mathematician by the name of Leibniz made a similar machine that could multiply and divide as well. After about 150 years, a mathematician at Cambridge, Charles Babbage made his Difference Engine. -

On the Efficacy of Source Code Optimizations for Cache-Based Systems
On the efficacy of source code optimizations for cache-based systems Rob F. Van der Wijngaart, MRJ Technology Solutions, NASA Ames Research Center, Moffett Field, CA 94035 William C. Saphir, Lawrence Berkeley National Laboratory, Berkeley, CA 94720 Abstract. Obtaining high performance without machine-specific tuning is an important goal of scientific application programmers. Since most scientific processing is done on commodity microprocessors with hierarchical memory systems, this goal of "portable performance" can be achieved if a common set of optimization principles is effective for all such systems. It is widely believed, or at least hoped, that portable performance can be realized. The rule of thumb for optimization on hierarchical memory systems is to maximize tem- poral and spatial locality of memory references by reusing data. and minimizing memory access stride. We investigate the effects of a number of optimizations on the performance of three related kernels taken from a computational fluid dynamics application. Timing the kernels on a range of processors, we observe an inconsistent and often counterintuitive im- pact of the optimizations on performance. In particular, code variations that have a positive impact on one architecture can have a negative impact on another, and variations expected to be unimportant can produce large effects. Moreover, we find that cache miss rates--as reported by a cache simulation tool, and con- firmed by hardware counters--only partially explain the results. By contrast, the compiler- generated assembly code provides more insight by revealing the importance of processor- specific instructions and of compiler maturity, both of which strongly, and sometimes unex- pectedly, influence performance. -

Yet, in contrast to nearly all other interfaces in a modern computer system, all commercially popular ISAs are proprietary.
