High performance PA-RISC Snakes motherboard I/O

摘要

A low-cost, high-performance motherboard I/O design has been developed. The design consists of 93 K gates spread across three ASIC chips and a number of PC boards. Key features of the desktop and deskside design include 20 MByte/s Fast-Wide SCSI-2, link rate FDDI, and CD quality audio. Overall motherboard disk performance was increased by a factor of four and motherboard network performance by a factor of ten. This was done while adding new CD-audio features.
