PCI Bridge/CPU
MegaRAID Express 500 uses the Intel i960RM PCI bridge with an embedded 80960JX RISC processor running at 100 MHz. The RM bridge handles data transfers between the primary (host) PCI bus, the secondary PCI bus, cache memory, and the SCSI bus. The DMA controller supports chaining and unaligned data transfers. The embedded 80960JX CPU directs all controller functions, including command processing, SCSI bus transfers, RAID processing, drive rebuilding, cache management, and error recovery.
