A Versatile Computation Module for Adaptable Multimedia Processors

Abstract

Abstract-This paper describes a low cost, low power, versatile computation module that can be used as a coarse-grain building block in multimedia processors. The module, which has a datapath and a controller integrated with its local data memory, performs various arithmetic operations on different data types, i.e., 8-bit integer, 16-bit integer, 32-bit integer and single precision floating point numbers. Running in parallel, the module provides high data throughput at low hardware cost. Multiple modules will be connected in a multimedia processor operated in mixed SIMD and MIMD modes, providing great flexibility for data parallel, computation intensive multimedia applications.
