A horizontal architecture computer in which a plurality of instructions are selectively communicated to a processing unit simultaneously or sequentially. The computer includes a processing unit with a plurality of processors, an instruction unit with a plurality of storage locations for storing instructions, and means for communicating the instructions to the processors. A first connection circuit provides a plurality of parallel communication channels between the storage locations and the processors and a second connection circuit provides a single serial communication channel between the storage locations and the processors. The first circuit is selected if a multioperation instruction is to be executed, otherwise the second circuit is selected instead.
