Abstract

Lapped Orthogonal Transforms (LOT) are becoming more widely used in image coding applications for image transmission and archival schemes. Previously sponsored U.S. Army Missile Command research has developed a LOT Recursive Residual Projection (RRP) that uses the following multiple bases functions: Discrete Cosine Transform (DCT), Discrete Walsh Transform (DWT), and Discrete Slant Transform (DST). For high compression ratios the LOTRRP was shown no outperform the single bases transforms at the cost increased computations. The work presented in this paper describes a VHSIC Hardware Description Language (VHDL) design of the LOTDCT, LOTDWT, and LOTDST targeted for implementation on Application Specific Integrated Circuits (ASICs). This hardware solution was chosen to compress RS-170 standard video for real-time image transmission on a very low bandwidth packetized data link.
