The present invention provides an information processing apparatus and an integrated circuit which realize parallel execution of different processing systems, and which do not require the provision of a dedicated memory storing instructions for common processing The information processing apparatus comprises: a plurality of processor elements; an instruction memory storing a first program and a second program; and an arbiter interposed between the processor elements and the instruction memory, the arbiter receiving, from each of the processor elements, a request for an instruction, from among instructions included in the first program and the second program, and controlling access to the instruction memory by the processor elements, wherein the arbiter arbitrates requests made by the processor elements when the requests are (i) simultaneous requests for different instructions included in one of the first program and the second program or (ii) simultaneous requests for an instruction included in the first program and an instruction included in the second program, and when two or more of the processor elements simultaneously request a same instruction included in one of the first program and the second program, the arbiter, when judging that the instruction memory is available to the two or more processor elements, outputs the same instruction to the two or more processor elements.
