This paper discusses some of the major performance differences between the MPC8240Õsmemory 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 thetwo parts which impact performance.Ñ The MPC8240 offers faster memory and PCI buses and features PCI datastreamingcapabilities.Ñ The MPC106 supports an external L2 cache, but this may result in lowermemory bus speed.¥ Part 2ÒSimulation,Ó presents results from an analytical model used to comparevarious system conÞgurations which highlight these architectural differences.
