This work proposes a novel produced order parallel queue processor architecture. To store intermediate results, the proposed system uses a FIFO queue registers instead of random access registers. Datum is inserted in the queue in produced order scheme and can be reused. We show that this feature has a profound implication in the areas of parallel execution, programs compactness, hardware simplicity and high execution speed. Our preliminary performance evaluations have shown a significant performance improvement (e.g., 10% to 26% decrease in program size and 6% to 46% decrease in execution time over a range of benchmark programs) when compared with the earlier proposed architecture.
