Abstract

Control unit for computer processor, in which microinstructions corresponding to the instantaneous of a user programme are decoded, deliver a control signal conforming to this decoding by which data processing of the user programme in the processor and principal memory is effected. In order to increase the number of functions which the micro-instructions can execute a variable content control function register is provided which from the moment of micro-instruction decoding furnishes data which is associated with it to a decoder which forms the function to be executed from data contained in the micro-instruction and in the function control register.
