Abstract
A racing circuit wherein request signals which are asynchronously and simultaneously generated by a plurality of processor units for requesting the use of a common resource such as a memory are temporarily stored, and one of the stored request signals is selected so that the corresponding processor unit may access and use the common resource. The circuit provides a buffer arrangement for causing a first received request signal to lock out other request signals which follow the first signal too closely, and for providing access to the common memory or other device in the order in which access requests were received. The processor unit may control the racing circuit so that the processor unit may attain the exclusive use of the common resource as long as it desires.
