Title: Peripheral controller
Inventor: MORI YOSHIAKI
IPC: G06F13/12
Filed: 1995-02-15
Abstract: PURPOSE: To provide a peripheral controller capable of making plural connected peripheral units execute well-balanced processing regardless of difference of throughput between a host device and the peripheral unit. CONSTITUTION: The continuous number of times of acceptance of an input/ output instruction from each host device is counted by startup request counters 22, 23. When the count value of the start-up request counters 22, 23 reaches an upper limit value stored in a threshold value register 24 and capable of accepting the input/output instruction continuously, the input/output instruction is disabled to accept even when it arrives. In place of the acceptance of the input/output instruction, it is checked whether or not the processing of awaiting state is performed, or the peripheral unit is changed to a state executable the input/output instruction.  Since an opportunity to check the presence/absence of the instruction set in the awaiting state is provided compulsorily even when the input/output instruction arrives continuously from the host device, the case to lose balance in the progress of processing is reduced.
