Abstract

PURPOSE: To prevent processing capacility over even for execution of a new processing by providing a means, which calculates the total throughput of an operating device, in the channel control unit.
CONSTITUTION: The throughput value of a started device is inputted to throughput register TR1 by the start indication from a CPU, and data of TR1 is inputted to throughput in register TIR4 by SEL circuit 2. Operator 5 adds the value of total throughput register TTR6, where the current total throughput value, and the TIR start throughput value and inputs the result to throughput out register TOR7. Decision circuit 8 used data of TOR7 as an input to compare it with the maximum throughput of the channel control unit. If data of TOR7 is smaller than the maximum throughput, the value of TOR7 is inputted to TTR6, and the throughput value of a new started device is stored in the storage area of SBCH3 to accept the device. If not, a processing capability over signal is returned to the CPU.
