Abstract
A shared write back buffer for storing data from a data cache to be written back to memory. The shared write back buffer includes a plurality of ports, each port being associated with one of a plurality of processing units. All processing units in the plurality share the write back buffer. The shared write back buffer further includes a data register for storing data provided through the input ports, an address register for storing addresses associated with the data provided through the input ports, and a single output port for providing the data to the associated addresses in memory.
