Aspects of the subject disclosure may include, for example, a rate distortion optimized quantization module that includes a transform coefficient level selector configured to select transform coefficient levels by evaluating a plurality of candidate transform coefficient levels based on distortion data from a distortion module and BAC data from a BAC module. The distortion module and the BAC module store a plurality of partial results in a partial result cache in conjunction with processing ones of the plurality of candidate transform coefficient levels and reuse the plurality of partial results from the partial result cache in conjunction with processing of subsequent ones of the plurality of candidate transform coefficient levels. Other embodiments are disclosed.
