Abstract :
A new hard disk controller (HDQ) LSI for 16/32-bit personal computers has been developed. The key feature of the controller is its on-chip DMA capability. The LSI operates as a channel processor based upon a Channel Control Word (CCW) scheme as well as a hard disk controller. Over 1.75-Mbyte/s disk data speed and over 6.6-Mbyte/s host bus data speed were obtained simultaneously.
