Paper Abstract

We propose EVLIW as a new processor architecture which is designed for general purpose processing and is suitable especially for real-time image processing. The processor architecture is a VLIW, but it has more functional units than the generic VLIW processor has. The EVLIW consists of the interconnection network for connecting the neighbor and of functional units, which are more primitive than in the generic VLIW processor. Some of general-purpose processors in the market includes several processing units, e.g. the same four single precision floating-point or four 16bit-word integer units for Intel processor with SSE/MMX, where the four units do the same operation with the four different data. In the image processing, the data are processed in parallel, where the operating is not complicated an only the high-speed processing is usually required. We have tried a simple image processing using Intel's processor with SSE/MMX and summarize the results. In this paper, we describe a new architecture for real-time imaging, and its design, comparing with Intel's processor with SSE/MMX.
