A processing device includes an imitation multiport memory circuit (10) interconnecting inputs and outputs of a group of functional units (F1,...FN), all operating under 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 memory units. The memory circuit (10) provides substantially the same performance as a true multiport memory but requires a smaller circuit area, allowing a larger processing device to be integrated in one chip than previously.; Collisions for access to a memory unit write port can be resolved without rescheduling by use of a delay element (21,70) and/or an additional write port (82) to a memory unit.
