ABSTRACT:
A flexible computer controlled non-linear transform generator is disclosed which employs a random access memory (RAM) lookup table (LUT) having programmable controlled address and data paths and an address multiplexer which is programmed to dynamically control LUT loading and live data transformation. A MASK register is programmed to dynamically modify the number of banks of memory in the LUT, an ADDRESS SELECT register is programmed to set the access mode of for the LUT--either random access mode, auto-increment mode, or live data mode, a BIT WIDTH register is programmed to set the width of the data stored in the LUT, and a BASE ADDRESS register is programmed with the starting address for loading the LUT in auto-increment mode. During live data transformation, a digitized input signal is used to address the LUT, while the contents of the LUT at the addressed location provides a digitized output signal according to a predefined transfer function. During LUT loading, transform data for different transfer functions may be stored in different banks of the LUT. Thereafter during live data transformation, the transform generator's transfer function can be quickly changed by reprogramming the MASK register to switch LUT banks.
