GT-64111 System Controller for RC4640, RM523X and VR4300 CPUs
78
Revision 1.0
15.2
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/Local Master can read from the DRAM at peak bandwidth of 264Mbytes per second. CPU/Local
Master writes have peak bandwidth of 264Mbytes per second for all devices through the GT-64111 on-chip write buffer.
