A vector processing computer is configured to operate in a pipelined fashion wherein each of the functional units is essentially independent and is designed to carry out its operational function in the fastest possible manner. Vector elements are transmitted from memory, either main memory, a physical cache unit or a logical cache through a source bus where the elements are alternately loaded into the vector processing units. The vector control unit decodes the vector instructions and generates the required control commands for operating the registers and logical units within the vector processing units. Thus, the vector processing units essentially work in parallel to double the processing rate. The resulting vectors are transmitted through a destination bus to either the physical cache unit, the main memory, the logical cache or to an input/output processor. In a further aspect of the computer there is produced an entry microword from a store for the immediate execution of the first microinstruction within a sequence of microinstructions. The remaining microinstructions are produced from a conventional store. This reduces the delay in the retrieval and execution of the first microinstruction. In a still further aspect of the computer there is included the logical data cache which stores data at logical addresses such that the central processor can store and retrieve data without the necessity of first making a translation from logical to physical address.
