11.2 Typical System
The high performance system shown below includes 64-bit wide memories and 32-bit I/O devices on the PCI bus. The
system includes Flash for storing code and data, and DRAM as main memory. In this system data can be moved via
DMA or PCI master accesses between the PCI bus and the Flash or DRAM at full bus bandwidth, at 200 Mbytes per
second. The CPU can read from the DRAM at peak bandwidth of 200Mbytes per second. CPU writes have peak band-
width of 400Mbytes per second for all devices through the GT-64010A on-chip write buffer.
