PCI Bridge/CPU
RAID Controller Kit-G uses the Intel GC80302 PCI bridge with an embedded 80960JT
RISC processor running at 66 MHz. The GC80302 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 80960JT CPU directs all controller functions, including command
processing, SCSI bus transfers, RAID processing, drive rebuilding, cache management,
and error recovery.
