Title:
DATA PROCESSING UNIT HAVING HARDWARE-BASED RANGE ENCODING AND DECODING
Document Type and Number:
WIPO Patent Application WO/2020/092788
Kind Code:
A3
Abstract:
A highly programmable data processing unit includes multiple processing units for processing streams of information, such as network packets or storage packets. The data processing unit includes one or more specialized hardware accelerators configured to perform acceleration for various data-processing functions. The data processing unit is configured to retrieve speculative probability values for range coding a plurality of bits with a single read instruction to an on-chip memory that stores a table of probability values. The data processing unit is configured to store state information used for context-coding packets of a data stream so that the state information is available after switching between data streams.
