摘要：A processing device includes an imitation multiport memory circuit (10)interconnecting inputs and outputs of a group of functional units (F1,...FN), all operatingunder control of a single series of very long program instructions. The memory circuit(10) comprises a plurality of separate memory units (15), each having a read port (12)connected to a respective functional unit input, and a crossbar switching circuit (18)connected between the functional unit outputs and write ports of the separate memoryunits. The memory circuit (10) provides substantially the same performance as a truemultiport memory but requires a smaller circuit area, allowing a larger processing deviceto be integrated in one chip than previously. Collisions for access to a memory unit writeport can be resolved without rescheduling by use of a delay element (21,70) and/or anadditional write port (82) to a memory unit.
