ABSTRACT:
A data processor having a string operation instruction and a bit map operation instruction, and comprises a bus interface unit 157 which inputs/outputs data by the burst transfer function, and an integer operation unit 155 building-in a main ALU and a sub-ALU, wherein data is repeatedly transferred to/from an external memory via a data bus 102 in unit greater than a width of the data bus 102. Further, is can be accessed in a high speed by the block transfer in the burst mode to efficiently execute the above instructions, therefore the data string and bit map data can be executed quickly even when a low-cost slow memory system is connected thereto.
