Abstract
PURPOSE: To restrain the time delay due to error correction within 1t, by generating the end signal at the timing after decoding of the corrected micro instruction in the decoder when error display is performed.
CONSTITUTION: After the micro instruction read from control storage device 1 is set to instruction register 6 without error correction, the decoding processing of decoder 7 is started. If an error exists, presence or absence of the error is decided, and processing synchronizing part 10 delays generation of the micro instruction end signal by 1t and generates the decode end signal at the following timing. During this time, the corrected micro instruction is set to instruction register 6 and is decoded by decoder 7 to execute the micro instruction. By utilizing that 1t is required for setting the instruction from data register 3 to instruction register, the time delay due to error correction is restrained within it.
