PROBLEM TO BE SOLVED: To reduce the number of gates in a register and efficiently process a plurality of tasks or threads in a processor for pipeline processing. SOLUTION: A pipeline processor 1 is provided with a memory 100 for a register comprised of memories instead of register files, as well as a memory 30 for a program counter comprised of memories instead of registers constituting a PC. Therefore, when compared with a case in which the memories are comprised of registers, the number of gates in the register can be reduced, and the context can be switched by specifying an address without exchanging the context, so that a plurality of tasks or threads can be efficiently processed.
