Efficient integrated circuits configuration data management
First Claim
1. Configuration circuitry comprising:
- a decoding circuit that receives a base configuration data set and a first data set, wherein the first data set includes compressed data differences between the base configuration data set and a decoded configuration data set, and wherein the decoding circuit comprises;
a first circuit that receives the first data set and that decompresses the first data set to create a second data set; and
a second circuit that receives the base configuration data set and the second data set from the first circuit and that outputs the decoded configuration data set using the base configuration data set and the second data set.

Abstract
Circuitry for efficient configuration data management is presented. The circuitry includes an encoding circuit that compares configuration data of a circuit design with base configuration data of a base circuit design. The encoding circuit compresses the difference between the configuration data and the base configuration data to produce compressed configuration data. The compressed configuration data can be stored in a storage circuit. For a purpose of implementing the circuit design in an integrated circuit, a decoding circuit can retrieve the compressed configuration data from the storage circuit, decompress the compressed configuration data, and compare the result of a decompression operation with the base configuration data to restore the configuration data. The restored configuration data can serve to program configuration memory bits on the integrated circuit, thereby implementing the circuit design.
