1.2.1 SCSI Performance
To improve SCSI performance, the LSI53C810A:
Complies with PCI 2.1 specification
Supports variable block size and scatter/gather data transfers
Minimizes SCSI I/O start latency
Performs complex bus sequences without interrupts, including
restore data pointers
Reduces Interrupt Service Routine (ISR) overhead through a unique
interrupt status reporting method
Performs fast SCSI bus transfers in SE mode
up to 7 Mbytes/s asynchronous
10 Mbytes/s synchronous
Increases performance of data transfers to and from the chip
registers with new load and store SCRIPTS instruction
Supports target disconnect and later reselect with no interrupt to the
system processor
Supports execution of multithreaded I/O algorithms in SCSI
SCRIPTS with fast I/O context switching
