Computer system apparatus for stabilizing asynchronous interfaces |
摘要 |
A computer system apparatus for asynchronous data transfer between a source and sink without the use of an asynchronous control signal. includes metastability circuits, data change detection logic, a stability window delay counter, and a mux/register pair to allow for the holding of previous stable data during the transition. While the processing logic employed specifically applies to asynchronous logic, the logic can be extended to synchronous or untimed interfaces as well. Also disclosed is a programmable means to adjust the window delay.
