Comparative VME Performance Tests for MEN A20 Intel-L865 and RIO-3 PPC-LynxOS platforms

This benchmark note presents test results from reading values over VME using different methods and different sizes of data registers, running on two different platforms Intel-L865 and PPC-LynxOS. We find that the PowerPC is a factor 3 faster in accessing an array of contiguous VME memory locations....

description This benchmark note presents test results from reading values over VME using different methods and different sizes of data registers, running on two different platforms Intel-L865 and PPC-LynxOS. We find that the PowerPC is a factor 3 faster in accessing an array of contiguous VME memory locations. Block transfer and DMA read accesses are also tested and compared with conventional single access reads.
