Method and system for determining which memory locations have been accessed in a self timed cache architecture |
摘要 |
The present invention provides a method and system for providing observability of memory address access for self-timed cache designs. A system according to the present invention for determining which memory location has been accessed in a self-timed cache comprises a content addressable memory; a secondary memory coupled to the content addressable memory, wherein the secondary memory includes at least one memory location which may be selected by the content addressable memory based upon a self-timed cache access. The system further includes a test circuitry coupled to the content addressable memory, wherein the test circuitry stores a pointer which points to a selected memory location in response to the self-timed cache access of the secondary memory. |
