The 80C286/883 is an advanced, high-performance microprocessor with specially optimized capabilities for multiple user and multi-tasking sys- tems. The 80C286/883 has built-in memory protection that supports operating system and task isolation as well as pro- gram 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 super- set of the 80C86/80C88 instruction set). Using the 80C286/ 883 real address mode, the 80C286/883 is object code com- patible with existing 80C86 and 80C88 software. In protected virtual address mode, the 80C286/883 is source code com- patible with 80C86 and 80C88 software but may require upgrading to use virtual address as supported by the 80C286/883’s integrated memory management and protec- tion mechanism. Both modes operate at full 80C286/883 performance and execute a superset of the 80C86 and 80C88 instructions. The 80C286/883 provides special operations to support the efficient implementation and execution of operating systems. For example, one instruction can end execution of one task, save its state, switch to a new task, load its state, and start execution of the new task. The segment-not-present excep- tion and restartable instructions.
