Abstract
A multiprocessing system that uses read resources to track cache coherent split transactions on its main system bus. Pending reads are tracked by being associated with read resources. When a read request is issued, it occupies the first available read resource. A pending read request will occupy a read resource until a corresponding read response appears on the bus. If all read resources are filled, future read requestors must wail until a read resource becomes available.
