Abstract
PURPOSE: To make logging possible without any address stop by providing a circuit that causes an interruption when the contents of logging address register LAR agree with the address of microprogram μPG in process of execution.
CONSTITUTION: Through the panel, address A of μPG where logging to be carried out is previously set in LAR8 and when the contents of address register AR2 agree with those of LAR8, comparing circuit 9 sends an identity signal to set FF10 while interruption control circuit 11 sends a signal to address control circuit 1. Circuit 1 transfers contents A+1 of AR2 to address stand-by register 7 and sets the start address of new μPG in AR2. The new μPG stores information on the internal register and others in the logging area of control storage 3, read address B of μPG, at which the next logging is to be executed, out of memory unit 12, and sets and reset LAR8 and FF10 respectively. Next, address A+1 is returned from register 7 to AR2 and the original μPG is executed.
