Abstract
Arrangement of circuits for addressing a microprogram of data processing facilities, by reading instruction words from an instruction memory, controlled step by step by a register of instruction addresses, and evaluation of instruction words in relation to the program routines to be carried out within the microprogram, using instruction words with individual groups of functions, functionally independent of each other, and an instruction register with register sections and outputs of divided sections is arranged after the instruction memory according to the number of groups of functions, characterized in that the outputs (A, B, C, D, E) of the sections are led to a multiplexer (14), whose multiplex output provides a part of a micro-address to be entered in a register (15) of micro-addresses, the multiplexer (14) being controlled by control signals of a link logic (20), which is activated by microprogram block addresses and status signals of the data processing installation.
