The Intel386 CPU family-architecture and performance analysis
Tejpal Chadha, P. Srinivasan · 2003
The authors present a synopsis of the various performance metrics related to the i386 CPU architecture. The complex i386 CPU architecture has a number of factors which determine the overall performance of a job. A rich set of tools has been developed to analyze the i386 architecture and its performance. Using these tools and methodologies, it is shown how an average number like CPI (cycles per instruction) can vary over the run time of the job. All the results presented are for the Intel486 DX microprocessor, executing the four integer benchmarks in the SPEC 1.0 benchmark suite.>
