Summary

• Can have only one fragment processor if the following conditions are met:

  • Fragment processor clock frequency > Fragment Rate
    • Assumes fragment ops are fully pipelined
      • This costs us in terms of gates, assumes we have gates to spare
    • Framebuffer update Rate > Fragment Rate
      • Framebuffer update Rate = 1/2 * memory access time.

• If conditions not met, need to have parallel Fragment processors
