Context value retrieval prior to or parallel with expansion of previous symbol for context-decoding in range decoder

摘要

A highly programmable device, referred to generally as a data processing unit, having multiple processing units for processing streams of information, such as network packets or storage packets, is described. The data processing unit includes one or more specialized hardware accelerators configured to perform acceleration for various data-processing functions. This disclosure describes examples of retrieving values represented by one or more previous symbols needed for decoding a current symbol before or in parallel with the insertion of the values represented by the one or more previous symbols in the data stream.
