DATA PROCESSOR

PURPOSE:To execute a program with high efficiency without using a command analyzing routine by using a command table, a command table register and a command table retrieving mechanism. CONSTITUTION:A command table retrieving mechanism 8 refers to a command table register 7 and confirms from an identification address set previously that a command table 6a is equal to a desired one. While a designated command is taken out with reference to the contents of a parameter table register 3, i.e., the address of a parameter table 2. An execution start address of a command processing routine 5a corresponding to a designated command is taken out with the retrieval of the table 6a and set to an instruction pointer register 1. Thus the routine 5a is executed and all actions are completed through each proper processing.
