Patent ID: 8731051

Claim:
A video processor for implementing quantization, said video processor comprising: an input for receiving data, wherein: said data comprises a plurality of values to be quantized; and an internal register for storing said data; and a quantizer, comprising quantization lookup tables and configured to receive Single Instruction Multiple Data (SIMD) instructions, wherein: upon receiving a first quantization SIMD instruction, said quantizer is operable to perform a plurality of top-level quantization decisions with respect to said plurality of values, wherein said plurality of top-level quantization decisions comprises determining a lookup table applicable to the plurality of values being processed; upon receiving a second quantization SIMD instruction, said quantizer is operable to identify a plurality of quantization values appropriate to said plurality of values; and upon receiving a third quantization SIMD instruction, said quantizer is operable to quantize said plurality of values.
