G-MAC: An Application-Specific MAC/Co-Processor Synthesizer

: A modern special-purpose processor (e.g., for image and graphical applications) usually contains a set of instructions supporting complex multiply-operations. These instructions perform a variety of multiply-operations with various data bitwidths and concurrent-execution requirements. For instance, such an instruction set may include instructions to perform signed/unsigned 32X32, signed/unsigned dual 16X16, signed/unsigned 8X8 MAC, and etc. Typically, a co-processor or a complex MAC (Multiplier-ACcumulator) unit is required to execute those instructions. Developing such a complex MAC/co-processor involves a series of design tasks including micro-architecture design, component allocation/binding, interconnect binding, pipeline insertion and control generation. This design process is non-trivial, time-consuming and error-prone, which is usually performed by experienced design engineers. In this paper, we present a synthesis method for application-specific MAC/coprocessor generation. Th...
