A method for designing high-radix multiplier-based processing units for multimedia applications

摘要

Multifunctional architecture for video and image processing (MAVIP) to be used in multimedia systems are proposed. MAVIP is a family of reconfigurable architectures derived from a single high-radix (4, 8, or 16) multiplier structure where: a) the list of potential partial products obtained at the first stage of multiplication may be reused; b) pipeline stages may be parallelised at different level to achieve required clock frequency and to improve balancing between these stages; and c) interconnections between the operational blocks may be multiplexed to make the structure multifunctional and to allow reusing basic multiplier blocks. The same device may operate either as a programmable processing unit with digital signal processor-specific operations or as a reconfigurable ASIC. Being small, MAVIP indicates competitive performance in video coding applications.
