Patent ID: 7073031

Claim:
A system, comprising: a plurality of processors; a plurality of resources, one portion of the resources being sharable with the plurality of processors and each one of the other ones of the resources being dedicated to a predetermined one of the processors; a plurality of buffers, each one of the buffers being associated with a corresponding one of the plurality of processors, each one of the buffers being adapted to successively store information presented thereto in successive locations of such one of the buffers, such information including requests from the corresponding one of the processor; a logic section responsive to each one of the requests provided by the plurality of processors for producing an indicia indicating whether or not such one of the requests is a request for an operation with one of the sharable resources, such logic section inserting said indicia into a succeeding one of the locations of the buffers associated with such one of the processor providing such one of the requests and for simultaneously inserting such indicia into a next succeeding available location of the other ones of the plurality of buffers, such logic section inhibiting execution of requests in the buffers stored in locations thereof succeeding the location having stored therein any such inserted indicia.
