PURPOSE:To branch to an optional program easy, by constituting a sub-memory block to a form modified accessibly at an address section of the instruction of a branch section fetching the loading information when the sub-memory block is loaded. CONSTITUTION:A memory MEM stores various programs and consists of blocks BL0, BL1... and each block is formed on a different printed board. An instruction read out from any block of the memory MEM is fetched to an instruction register REG1, and its address is used for the address of the memory MEM again through an address producing circuit CONV, a produced address register REG2, and an instruction address register REG3. When this address is not branched to the optional program, it passes through the circuit CONV. When this address is the branched address, the address is modified with loading information C1, C2... of blocks BL1, BL2.... |
