Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To evade an unnecessary request arbitration wait time and to gain efficient memory access by preferentially arbitrating a request from another requester on condition that the request can be sent out while a request from one requester can not be arbitrated. SOLUTION: In the case that although a request sending-out part 10 receives a request at the time of request conflict, the request can not be sent out of the request sending-out part 10 because of the limitation of a reply buffer 30, a request issued by a requester other than a data processing part AO is preferentially arbitrated when meeting the conditions of a subtraction result. Therefore, the request which can be sent out to a storage device are preferentially be arbitrated and processed according to the use state of the reply buffer 30. Consequently, the unnecessary request arbitration wait time is evaded and maximum data transfer is secured to actualize data transfer with good efficiency of the whole system.

Abstract: PURPOSE:To surely start read of a data from an object address (AD) by designating an AD smaller than a current AD by a prescribed AD again when the current AD is larger than an object AD at the start of read after search. CONSTITUTION:A processor uses a head AD of a map data corresponding to an inputted map number as an object AD, designates it as a header AD and gives it to a player controller 13 together with a read command. The controller 13 searches the object AD based on a sub code AD obtained from read information while moving a pickup 6 in the direction of the object AD. When the current AD obtained from a decoder 16 is coincident with the object AD, the processor gives a read start command of a disk to the controller 13. When the current AD is larger than the object AD, an AD smaller than the current AD by a prescribed AD is designated as a new object AD again, a designation flag is set and the search processing of the object AD is executed again.
