Paper Abstract

This paper summarizes techniques for mapping blockwise compression transforms such as EBLAST, JPEG, Visual Pattern Image Coding, and vector quantization to reconfigurable architectures such as field-programmable gate arrays. The distinguishing feature of this study is that computational precision is varied among different operations within a given transform. For example, we found that a four-bit block sum is sufficient to compute EBLAST accurately using encoding blocks as large as 10 X 10 pixels. In contrast, image-template convolutions constituent to EBLAST compression and decompression require seven- to eight-bit fixed-point operations.
