Efficient asynchronous bundled-data pipelines for DCT matrix-vector multiplication.

This paper demonstrates the design of efficient asynchronous bundled-data pipelines for the matrix-vector multiplication core of discrete cosine transforms (DCTs). The architecture is optimized for both zero and small-valued data, typical in DCT applications, yielding both high average performance a...
