Performance Differences between the MPC8240 and the MPC106 Top Changwatchai and Roy Jenevein risc10@email.sps.mot.com This paper discusses some of the major performance differences between the MPC8240Õs memory and PCI interfaces and those of the MPC106. This document compares theMPC8240 (rev. 1.0) the MPC106 (rev. 4.0). It contains the following:¥ Part 1ÒArchitectural Differences,Ó discusses architectural differences between the two parts which impact performance.Ñ The MPC8240 offers faster memory and PCI buses and features PCI datastreaming capabilities. Ñ The MPC106 supports an external L2 cache, but this may result in lower memory bus speed.¥ Part 2ÒSimulation,Ó presents results from an analytical model used to compare various system conÞgurations which highlight these architectural differences.
