Methods and arrangements for multi-buffering data

Abstract

Embodiments may comprise logic such as hardware and/or code within a heterogeneous multi-core processor or the like to coordinate reading from and writing to buffers substantially simultaneously. Many embodiments include multi-buffering logic for implementing a procedure for a processing unit of a specialized processing element. The multi-buffering logic may instruct a direct memory access controller of the specialized processing element to read data from some memory location and store the data in a first buffer. The specialized processing element can then process data in the second buffer and, thereafter, the multi-buffering logic can block read access to the first buffer until the direct memory access controller indicates that the read from the memory location is complete. In such embodiments, the multi-buffering logic may then instruct the direct memory access controller to write the processed data to other memory.
