SCSI I/O processor. It is designed to connect gluelessly to the Peripheral
Component Interconnect (PCI) bus. A drop-in replacement for the industry
standard LSI53C810, the LSI53C810AE transfers 8-bit SCSI data at speeds
as high as 7 MBps asynchronous and 10 MBps synchronous, while adding
features to further improve performance and enhance flexibility. The device
performs burst transfers on the PCI bus in excess of 110 MBps. The
LSI53C810AE provides full SCSI-2 capabilities, including command queuing,
and features LSI Logic’s TolerANT
reliable operation in all cabling environments.
a total SCSI solution in PC and workstation environments. LSI Logic’s SDMS
software package supports the entire LSI53C8XX family of PCI to SCSI
controllers, plus a wide range of SCSI peripheral devices.
SCRIPTS (the LSI Logic developed SCSI programming language) instruction
prefetch, which when enabled, permits fetching four or eight double words
of instructions or instruction operands. By pre-fetching instructions, the
LSI53C810AE makes more efficient use of the PCI system bus by reducing
the PCI bus overhead requirements. In addition, the part supports the PCI
Cache Line Size Register with programmable alignment logic and automatic
burst sizing, allowing system architects to maximize their cache-based system
performance through efficient use of PCI Memory Read Line, Memory Read
Multiple, and Memory Write and Invalidate access cycles. Other selectable
features that can be activated include:
• IRQ disable, allowing users to better control the times when their system
