Abstract
A system and method for processing data. According to a preferred embodiment, the system comprises a global memory and a plurality of datapaths. Each datapath comprises a datapath processor for executing instructions of an instruction sequence and for providing a plurality of memory request signal types in accordance with the instructions, local memory, a global port for transferring data between the local memory and the global memory, and a dual port comprising first and second local ports for transferring data between the local memory and the datapath processor, wherein the first and second local ports permit simultaneous transfer of data between the local memory and the datapath processor. The system comprises a data bus coupled to the global memory for transferring data to and from the global memory, and a transfer controller for controlling block transfer and scalar data transfers between the local memory and the global memory over the data bus and for arbitrating among competing datapaths of the plurality of datapaths to gram to a selected datapath access to the data bus in accordance with the signal types of the memory request signals generated by datapaths of the plurality …
