Abstract

PURPOSE:To obtain immediate data with long available bit length simply at a high speed by reading out the immediate data from a storage for data storing regarding the information held in a data field of a microinstruction. CONSTITUTION:An ordinary data processor is provided with an immediate data storing part 8. In an execution cycle of a read microinstruction, the contents of the data field MS, K field and ID field of a microprogram are accessed to an MS decoder 82, a K decoder 83 and an ROM81 through a bus 10 respectively. A required immediate data ID with 1 word length is sent as a data to be operated from the addresses of the ID field in the ROM81 to an operation module AM6 through a bus 11. The contents of a B field are applied to the right entrance of the module and the results of operation of both the operation data are stored in a register module.
