| 摘要 |
A variable speed controller is disclosed that is capable of processing selected commands at a faster-than-normal rate. The invention is useful in the context of x86-based microcomputers to speed up the execution of MASK-A20 and/or RESET-CPU commands that are normally carried out by an 8042-based controller. Execution time for these operations is improved, yet compatibility with existing peripherals and/or code is retained.
