CONTROL UNIT AND RECORDED MEDIUM

摘要

A control program constituted of a set of instructions having a first field where an execution instruction specifying data calculation executed by a control unit or another data processing can be written and a second field where a preparation instruction enabling the control unit to execute data calculation or another data processing can be written, whereby a preparation instruction independent of the execution instruction described in the first field is written in the second field. Such a set of instructions makes it possible to know the branch destination of a branch instruction in advance by writing the branch destination in a Y field, thus solving one of problems which a conventional set of instructions cannot solve.
