Performance Analysis of an H.263 Video Encoder for VIRAM
VIRAM (Vector Intelligent Random Access Memory) is a vector architecture processor with embedded memory, designed for portable multimedia processing devices. Its vector processing capability results in high performance multimedia processing, while embedded DRAM technology provides high memory bandwidth at low energy consumption. In this paper, we evaluate and compare performance of VIRAM to other digital signal processors (DSPs) and conventional SIMD (Single Instruction Multiple Data) media extensions in the context of video coding. In particular, we will examine motion estimation (ME) and discrete cosine transform (DCT) which have been shown to dominate typical video encoders such as H.263. We will show that VIRAM outperforms other architectures by 4.6x
