All Intel486 processors provide a rich instruction set for manipulating integer and floating point data. Special emphasis has been placed on providing optimized instructions for high- level languages and operating system functions. Multiple addressing modes ensure that high-level languages can be implemented in the most efficient manner possible. The integrated memory management unit supports virtual memory and demand paging. The on-chip translation lookaside buffer supports efficient paging.
Special instructions support memory-based semaphores.
Hardware-enforced cache line invalidations maintain consistency among multiple caches. Support for multilevel caches reduces bus utilization, allowing multiple Intel486 processors to share a single memory bus. Power and System Management Intel's SL Technology consists of a number of microprocessor features that deliver superior power management capabilities. The Intel486 processor brings the efficient Intel SL Technology to the embedded market segment. SL Enhanced Intel486 processors incorporate power-saving technology at the CPU level.
