Bus Interface Unit LSI (Large Scale Integrated) Chip Development
Abstract
This report describes a large scale integrated (LSI) circuit implementation of a serial data bus protocol. Two chips were designed to achieve all of the data bus interface functions. Chip type is concerned with sync generation/detection, encoding/decoding, terminal address/subaddress recogntiion, direct memory access (DMA) functions, first level error detection, and some mode code responses. This chip was produced in complementary metal oxide semiconductors technology. Chip type was concerned with the more complex bus controller functions including command word generation, data buffer address generation, time tagging of data, control codes, programmed interrupts, working registers, mode code responses, and second level error detect functions. Chip type was breadboard in TTL circuits but was not produced in LSI silicon.
