Abstract :
A PowerPC system-on-a-chip processor which integrates high speed state of the art 800 MHz PowerPC, DDRII-667 memory controller, RAID assist logic, and three PCI-X DDR266 interfaces with a rich mix of conventional peripherals is described. The PowerPC, with on-chip L2 cache enabled, executes up to 1600 DMIPS. The RAID assist logic is capable of transferring 2 Gbytes/sec. The state of the art PowerPC, the high bandwidth data pipes, and the RAID assist logic make the SOC an ideal solution for RAID controller applications. Active power consumption is as low as 6W with a 1.5 volt supply. The SOC has been implemented in a 0.13 μm, 1.5 V nominal-supply, bulk CMOS process.
