Abstract
The invention is related to methods and apparatus that decode convolutionally encoded data, including trellis-coded modulation (TCM) systems. One embodiment of the invention shares a memory device with a main processor, such as a microprocessor or a DSP, and advantageously relieves the main processor of the relatively time-consuming task of decoding the convolutionally encoded data. This frees up the main processor to execute other tasks. One embodiment of the invention includes a micro-coded state machine that can be programmed to control the decoding of the convolutional codes.
