Abstract

Register file (RF) has been widely used in latest DSP and media processors. It is very important to include a reasonable RF configuration in the processor designs to help reducing the chip area, consumption and architecture complexity. DSP and media processors need many direct accesses to memory, and this will reduce register accessing. Another kind of reducing RF accessing frequency is bypassing or forwarding implemented by software mechanism, that the successive following instructions can directly use the result produced by the previous one through bypassing logic rather than RF. Therefore, the RF accessing frequency is decreased further. According to the experiment result, this new RF configuration not only satisfies the requirements of traditional media processors, but also is well applied to media processors with very long instruction word (VLIW) architecture.
