Abstract
A method and apparatus including a plurality of data processing units. A plurality of memory banks having a shared address space are coupled to the processors by a crossbar coupling to enable reading and writing data between the processors and memory banks. A unidirectional network couples the memory banks and the processors to enable cache coherency messages to be transmitted from the memory to the processors. A plurality of semaphore registers are implemented within the shared address space of the memory banks wherein the semaphore registers are accessible by the processors through the crossbar coupling.
