  • Method and apparatus for concurrently accessing multiple memories with different timing requirements
    Patent number: 5625796
    Abstract: A data processing system in which a plurality of processors or other memory access devices operate either synchronously or asynchronously with a memory interface device, which in turn provides access to one or more memory units on a time-division basis. This is accomplished by providing each memory unit a series of time-divisioned access opportunities and controlling the phase relationship between these time-divisioned access opportunities. Accordingly, two or more access devices can address an equal number of memory units simultaneously.
