Product Overview 1-5
the flexibility requirements of SCSI-3 and future SCSI standards. It
executes multithreaded I/O algorithms with minimum host processor
intervention, reducing the protocol overhead required for SCSI operations
to as little as one interrupt per SCSI I/O. The SCRIPTS language, a high
level instruction set, provides complete programmability of I/O operations
and supports the flexibility needed for multithreaded I/O algorithms.
SCRIPTS provides:
•
Phase sequencing without processor intervention
•
Automatic bus arbitration
•
Data or phase comparison for independent SCSI algorithm decisions
•
DMA interface control
All LSI53C7XX/8XX/10XX family chips are also supported by LSI Logic
software for connecting SCSI devices. This includes BIOS support for
LSI Logic SCSI processors and drivers for most types of SCSI
peripherals under the major operating systems. These chips also feature:
•
On-chip Single-Ended (SE) drivers
•
Synchronous and asynchronous transfer capabilities
•
LSI Logic TolerANT
®
driver and receiver technology
•
Bus mastering
•
Automatic selection/reselection time-outs
•
32-bit memory addressing
•
32-bit data bus
•
PCI bursting
Newer chips, including the LSI53C895, LSI53C895A, LSI53C896,
LSI53C1000, LSI53C1010, LSI53C1010R, and LSI53C1000R also have
these features:
•
On-chip LVD
•
64-bit memory addressing
•
64-bit data bus
