Disclosed is a mixed mode parallel processor system in which N number of processing elements PEs, capable of performing SIMD operation, are grouped into M (=N÷S) processing units PUs performing MIMD operation. In MIMD operation, P out of S memories in each PU, which S memories inherently belong to the PEs, where P<S, operate as an instruction cache. The remaining memories operate as data memories or as data cache memories. One out of S sets of general-purpose registers, inherently belonging to the PEs, directly operates as a general register group for the PU. Out of the remaining S−1 sets, T set or a required number of sets, where T<S−1, are used as storage registers that store tags of the instruction cache.
