ARBITRATION CIRCUIT AND RECORDING MEDIUM DEVICE HAVING THE SAME BUILT IN

摘要

PROBLEM TO BE SOLVED: To smooth the pipeline processing a processing whose priority is low by compensating an access request and to accomplish an arbitration control that is not inconvenient, especially to recording and reproduction in real time. SOLUTION: When a frequency division clock obtained by performing frequency division of a reproduction clock or a recording clock from a disk part is inputted while requesters 101 and 102 output an access request REQ1, the requesters 101 and 102 output interrupt requests REQ1' and REQ2'. An adjusting part 201 receives such interrupt requests and allows the access requests of the requesters 101 and 102.
