A dual access digital storage device. |
摘要 |
<p>A two read-port, two write-port register file on a single integrated circuit chip provides dual read/write access via either an "A"-side or "B"-side of a single array of adressable registers. Separate on-chip "A"-side or "B"-side multiplexers permit reading or writing of an independently adressed register according to the phase of the "A"-side or "B"-side clock. Writing can be selctively effected to either a high-order and/or a low-order byte within the addressed register. Unidirectional busses connect each register to each of the four ports. The register can be expanded to provide a four read-port, two write-port register file such as is required for the parallel computation of addresses and data.</p> |
