ABSTRACT:
This circuitry permits equal access to a shared resource by a number of central processing units (CPUs). In a multiple CPU arrangement, common resource contention problems arise, when several CPUs attempt to access the common resource. To resolve these contention problems, this circuitry is an improvement to arbitration ring circuitry. The circuitry of this invention permits each of the CPUs equal access to the common resource during situations in which each CPU is constantly generating requests (high bandwith utilization) for access to the common resource. This invention is particularly useful for systems in which a large number of CPUs must have their local memory rapidly reloaded from a common memory source. Reloading procedures for large numbers of CPUs require up to an hour. By employing the present invention, these reloading times can be cut from one hour to approximately 5 minutes.
