Abstract

PURPOSE:To execute the character embedment processing efficiently, by calculating the first and second operand addresses, and length of their respective data by use of a corresponding address and a residual data length holding means, in case a long character moving instruction is executed. CONSTITUTION:When a data held by the first and second OP addresses is read out from the second OP address and is moved an address of the first OP, contents of the second OP are stored in an index register XR, and an address of the second OP is calculated by an effective address generator EAG. Also, the access byte length is decided in accordance with the first and second OPs, and residual length registers OP1L, OP2L, by an access byte length generating circuit ABLG. Contents of the first OP are set to a base register BR, the address calculation of the first OP and the access byte length are decided by EAG and ABLG, its results is held by a storage unit SU, and the second OP address is embedded in an address register of the first OP.
