Abstract

PURPOSE: To reduce the number of program steps by symbolizing a jump destination in case of the jump instruction of a program.
CONSTITUTION: The jump instruction of a program is formed by a code of the jump instruction and a code which has shortened the address of a fixed jump destination. The contents of the program address generator ASi are set to the program address part 14, the address to the program memory 16 is decided and a data from the memory 16 is stored in the latch Li, which are executed by CPU13 in accordance with a signal from the input unit. When the contents of the latch are sent into the jump discrimination part 17 and have been decided as the jump instruction, CPU13 processes a data obtained from the memory 16 as a symbol showing the jump destination, generates a control signal SAJi, sets the contents of the jump address generator AJi to the address part 14, and the contents according to this address are output from the memory 16.
