摘要:
A data processing apparatus includes a plurality of processing elements arranged in a single instruction multiple data array. The apparatus includes an instruction controller operable to receive instructions from a plurality of instructions streams, and to transfer instructions from those instructions streams to the processing elements in the array, such that the data processing apparatus is operable to process a plurality of processing threads substantially in parallel with one another. A data transfer controller is provided which is operable to control transfer of data between the internal memory units associated with the processing elements, and memory external to the array.
摘要:
A data processing apparatus includes a plurality of processing elements arranged in a single instruction multiple data array for processing data relating to graphical primitives. Vertex data relating to graphical primitives is used as feedback data for the processing elements for additional processing.
摘要:
A method of scheduling instruction streams in a SIMD (single instruction multiple data) array of processing elements in which the processing elements are arranged in a plurality of SIMD processing blocks, comprises determining which instruction stream has priority at a particular moment in time, and transferring that determined instruction stream to the SIMD array.
摘要:
A parallel data processing apparatus using a SIMD array of processing elements is disclosed. The apparatus makes use of a register in order to control issuance of instructions to the processing elements in the array.
摘要:
A method of processing data relating to geometrical primitives is disclosed. Each of the primitives has a plurality of vertices. The method uses a plurality of processing elements in parallel with one another, and comprises assigning respective vertex data to the processing elements, on each processing element, and in parallel with one another, performing at least one processing step on vertex data to produce processed vertex data, and transferring processed vertex data between processing elements so as to assemble primitive data.
