An implementation of trellis coded quantization (TCQ) of memoryless sources on dedicated digital signal processing hardware is described. The effect of encoding delay (i.e., the TCQ symbol release rule) on the overall encoding performance is evaluated. It is shown that quite modest encoding delays cause negligible loss in performance, compared to very long (e.g., 1000 sample) trellis search depths. The hardware requirements of TCQ encoding are discussed. A TCQ implementation on the DSP32 and TMS32020 digital signal processing (DSP) integrated circuits is described. Analytical expressions are provided for the per source sample implementation complexity (in clock cycles) for each DSP integrated circuit.
