  • Energy Per Instruction Trends in Intel® Microprocessors
    Energy per Instruction Trends in Intel® Microprocessors Ed Grochowski, Murali Annavaram Microarchitecture Research Lab, Intel Corporation 2200 Mission College Blvd, Santa Clara, CA 95054 [email protected], [email protected] Abstract where throughput performance is the primary objective. In order to deliver high throughput performance within a Energy per Instruction (EPI) is a measure of the amount fixed power budget, a microprocessor must achieve low of energy expended by a microprocessor for each EPI. instruction that the microprocessor executes. In this It is important to note that MIPS/watt and EPI do not paper, we present an overview of EPI, explain the consider the amount of time (latency) needed to process factors that affect a microprocessor’s EPI, and derive a an instruction from start to finish. Other metrics such as MIPS 2/watt (related to energy•delay) and MIPS 3/watt historical comparison of the trends in EPI over multiple 2 generations of Intel microprocessors. We show that the (related to energy•delay ) assign increasing importance recent Intel® Pentium® M and Intel® Core™ Duo to the time required to process instructions, and are thus microprocessors achieve significantly lower EPI than used in environments in which latency performance is what would be expected from a continuation of historical the primary objective. trends. 2. What Determines EPI? 1.

SUMMARY This report analyzes the feasibility of upgrading the Intel 386 a microprocessor, which has been proposed as the baseline processor for the Space Station Freedom (SSF) Data Management System (DMS), to the more advanced i486 a microprocessor. It is part of an effort funded by the National Aeronautics and Space Administration (NASA) Space Station Freedom Advanced Development program. The items compared between the two processors include the instruction set architecture, power consumption, the MIL-STD-883C Class S (space) qualification schedule, and performance. The advantages of the i486 over the 386 are lower power consumption and higher floating- point performance in speed. The i486 on-chip cache, however, has neither parity check nor error detection and correction circuitry. In space, the probability of having the contents of the cache altered, is higher than on the ground due to the higher radiation exposure. Therefore, it is necessary to measure the performance of the i486 with the cache disabled.

  • P5 (Microarchitecture)
    P5 (microarchitecture) The Intel P5 Pentium family Produced From 1993 to 1999 Common manufacturer(s) • Intel Max. CPU clock rate 60 MHz to 300 MHz FSB speeds 50 MHz to 66 MHz Min. feature size 0.8pm to 0.25pm Instruction set x86 Socket(s) • Socket 4, Socket 5, Socket 7 Core name(s) P5. P54C, P54CS, P55C, Tillamook The original Pentium microprocessor was introduced on March 22, 1993.^^ Its microarchitecture, deemed P5, was Intel's fifth-generation and first superscalar x86 microarchitecture. As a direct extension of the 80486 architecture, it included dual integer pipelines, a faster FPU, wider data bus, separate code and data caches and features for further reduced address calculation latency. In 1996, the Pentium with MMX Technology (often simply referred to as Pentium MMX) was introduced with the same basic microarchitecture complemented with an MMX instruction set, larger caches, and some other enhancements. The P5 Pentium competitors included the Motorola 68060 and the PowerPC 601 as well as the SPARC, MIPS, and Alpha microprocessor families, most of which also used a superscalar in-order dual instruction pipeline configuration at some time. Intel's Larrabee multicore architecture project uses a processor core derived from a P5 core (P54C), augmented by multithreading, 64-bit instructions, and a 16-wide vector processing unit. T31 Intel's low-powered Bonnell [4i microarchitecture employed in Atom processor cores also uses an in-order dual pipeline similar to P5. Development The P5 microarchitecture was designed by the same Santa Clara team which designed the 386 and 486.^ Design work started in 1989;^ the team decided to use a superscalar architecture, with on-chip cache, floating-point, and branch prediction.
