摘要： A method and apparatus for eliminating memory contention in a computation module is presented. The method includes, for a current operation being performed by a computation engine of the computation model, processing that begins by identifying one of a plurality of threads for which the current operation is being performed. The plurality of threads constitutes an application (e.g., geometric primitive applications, video graphic applications, drawing applications, etc.). The processing continues by identifying an operation code from a set of operation codes corresponding to the one of the plurality of threads. As such, the thread that has been identified for the current operation, one of its operation codes is being identified for the current operation. The processing then continues by determining a particular location of a particular one of a plurality of data flow memory devices based on the particular thread and the particular operation code for storing the result of the current operation. The processing then continues by producing a result for the current operation and storing the result at the particular location of the particular one of the data flow memory devices.

摘要： A method and apparatus for supporting shared microcode in a multi-thread computation engine is presented. Each of a plurality of thread controllers controls a thread of a plurality of threads that are included in the system. Rather than storing the operation codes associated with their respective threads and providing those operation codes to an arbitration module for execution, each of the thread controller stores operation code identifiers that are submitted to the arbitration module. Once the arbitration module has determine which operation code should be executed, it passes the operation code identifiers corresponding to that operation code to a microcode generation block. The microcode generation block uses the operation code identifiers to generate a set of input parameters that are provided to a computation engine for execution, where the input parameters correspond to those for the operation code encoded by the operation code identifiers received by the microcode generation block.

摘要： A pipeline apparatus for processing 3D graphics data will be described. The pipeline apparatus includes a first request memory to fetch information corresponding to a texture operand. A second request memory fetches information responding to a color operand and Z operand. A control circuit coordinates data flow from the first request memory and the second request memory into a memory channel by preventing the number of requests from the first request memory from exceeding by a predetermined number, the number of requests from the second request memory. By properly coordinating the data flow, deadlock of a data fetching pipeline is avoided.
