DESCRIPTION:
Maxwell Technologies’ 80386DX high performance 32-bit microprocessor features a geater than 100 krad (Si) total dose tolerance, dependent upon space mission. It is designed for very high performance and multitasking operating systems. The integrated memory management and protection architecture includes address translation registers, multitasking hardware and a protection mechanism to support operating systems. The 80386DX allows simultaneous running of multiple operations. In addition, the 80386DX is capable of execution at sustained rates of between 3 and 4 million instructions per second. It offers new testability and debu……
