Abstract:
1. A method for operating an encoder that produces a codeword (C) from an input vector (x), the method comprising the steps of: receiving, by a vector generator of the encoder, an input signal; creating, by the vector generator, the input vector; receiving, by a combinational coding circuitry of the encoder, the input vector to be encoded, wherein the input vector comprises speech, audio, image, or video signals; generating, by the combinational coding circuitry of the encoder, a first multi-precision operand (Ψ′ generating, by the combinational coding circuitry, a mantissa operand (M) and an exponent operand (h), wherein the mantissa operand and the exponent operand are representative of a second multi-precision operand (F′(p selecting, by the combinational coding circuitry, a portion of the first multi-precision operand to be modified based on the exponent operand; modifying, by the combinational coding circuitry, the portion of the first multi-precision operand based on the mantissa operand to produce a modified multi-precision operand (Ψ′ generating, by the combinational coding circuitry, the codeword (C) based on the modified multi-precision operand; wherein the codeword is for use by the encoder to encode the speech, audio, image, or video signals and by a corresponding decoder to decode the speech, audio, image, or video signals.
