Abstract
A multiprocessor data processing system in which a number of independent processors can concurrently operate on a shared memory even when one processor is performing a read-modify-write (RMW) operation, the system having a locking, content-associative write buffer and a controller for identifying RMW requests, for addressing the buffer and, for issuing directives to lock the buffer, to validate particular data blocks in the buffer and to transfer data back and forth between the processors, the memory and the buffer.
