Abstract
Techniques for providing a coefficient scaling operational unit to perform the coefficient scaling computation for various image compression schemes are disclosed. To minimize multiple units, each for one image encoding/decoding scheme (e.g., MPEG4 and WMV9), a single coefficient scaling operational unit is designed to accommodate various standards. In one embodiment, the coefficient scaling operational unit comprises an arithmetic logic unit. The arithmetic logic unit operates in accordance with a formula involving multiplication and division. Parameters such as coefficients and quantization parameters are provided to perform the coefficient scaling operation.
