1. A method for vector processing based quantization acceleration for an encoding process, comprising: computing coefficients for a discrete cosine transform encoding operation; determining a quantization step for use with a quantization operation for each of the coefficients; out of a range of possible quantized output values, computing a set of quantized output values from the coefficients by using a vector processor configured to evaluate each of the quantized output values of the set in parallel, wherein the vector processor comprises a plurality of comparators configured to determine a respective one quantized output value of the set of output values and configured to operate in parallel to compute a resulting quantized output value from the coefficients; for the range of possible quantized output values that are not computed using the vector processor, computing the quantized output values from the coefficients by executing multiplication logic; and transmitting the resulting quantized output values to the encoding process.
