This paper presents an experiment which aims to assess the potential impact on performance yielded by augmenting a TriMedia/CPU64 processor with a reconfigurable core. We first propose the skeleton of an extension of theTri-Media/CPU64 architecture, which consists of a Reconfigurable Functional Unit (RFU) and the associated instructions. Then, we address the computation of the 8脳8 IDCT on such extended TriMedia and propose a scheme to implement the 1-D IDCT operation on the RFU. When implemented on an ACEX EP1K100 FPGA from Altera, the proposed 1-D IDCT exhibits a latency of 16 and a recovery of 2 TriMedia (200 MHz) cycles, and occupies 42% of the device. By configuring the 1-D IDCT computing facility on the RFU at application load-time, a 2-D IDCT including all overheads can be computed with the throughput of 1/32 IDCT/cycle. This is an improvement of more than 40% over the standard TriMedia/CPU64. |
