Abstract
PURPOSE: To make branch control possible not by an instruction but by command chaining even when an input-output device sending end state information of different format is installed in one channel controller.
CONSTITUTION: After input-output device IO0 ends prescribed opereration, information stored in an address of private main memory unit MM of device IO0 is read out. On receiving operation end state information from device IO0, input-output controller IOC0 makes a check on a branch bit; when branch operation is not required, the address information is written as it is and when it is required, a branch-destination address is added to the address information by adder circuit ADX and then written to the exclusive-use address for IO0 of memory unit MM. From unit IOC0 to channel controller CHC, interruption request R is sent together with operation end state information I of IO0. Consequently, IOs differing in the pattern of the operation end state information can be mixed and installed in one CHC device, so that flexibility of CHC will increase.
