Abstract

PURPOSE:To simulate the operation environment of the execution of a microprogram by an input and output controller by providing a channel and a device part internally and associating them with the execution of instructions executed by a part DKC. CONSTITUTION:The channel part responds to the DKC with a channel interface signal as well as an actual channel. The channel part of a simulator further holds a channel command word (CCW) and its data internally so as to send commands to the DKC. By this function, commands are sent to the DKC by an external indication to perform data transfer. The device part makes adequate response corresponding to a Tag outputted from the part DKC. For the data transfer, a track format is formed internally. Said functions are divided into COM (command) units to realize them.
