Description

This is High Performance Microprocessor with Memory Management and Protection. 80C286, 883 March 1997 High Performance Microprocessor with Memory Management and Protection Description The Intersil 80C286, 883 is a static CMOS version of the NMOS 80286 microprocessor. The 80C286, 883 is an advanced, high-performance microprocessor with specially optimized capabilities for multiple user and multi-tasking systems. The 80C286, 883 has built-in memory protection that supports operating system and task isolation as well as program and data privacy within tasks. The 80C286, 883 includes memory management capabilities that map 230 (one gigabyte) of virtual address space per task into 224 bytes (16 megabytes) of physical memory. The 80C286, 883 is upwardly compatible with 80C86 and 80C88 software (the 80C286, 883 instruction set is a superset of the 80C86, 80C88 instruction set). Using the 80C286, 883 real address mode, the 80C286, 883 is object code compatible with existing 80C86 and 80C88 software. In protected virtual address mode, the 80C286, 883 is source code comp.
