Radiation Hardened Microprocessor. Volume II.
Abstract
The basic conclusion of this emulation analysis effort is that the GPU and its supporting devices (GUA, ROM and RAM) constitute a viable microprocessor bit slice device family. However, deficiencies were found in the GPU and its family members that must be rectified to ensure a truely competitive product line capable handling Air Force requirements. GPU design deficiencies are presently being corrected. Deficiencies in the breadth of the device family were also found to exist and recommendations for additional part types for the family are proposed. The most important additional device type required is a microprogram controller. Building a CMOS/SIS version of the AMD 2910 is recommended. A parallel effort was undertaken to define and design, to the gate level, a particular computer for emulation using the device family. This effort provided a test of the emulation capabilities of the device family. Further deficiencies in the devices were found as a result of this effort. The computer selected for emulation was the 8080--a microprocessor representative of the higher performance microprocessors on the market. A major accomplishment of this program was the detailed design of an 8080 emulator using the device family.
