Classification: CPC G  Y | IPC G

Claim 0:
1. A compression device comprising:
an analyzer circuit configured to analyze first data that is input thereto, determine an estimated power consumption in compressing and/or decompressing with respect to each of a sequence of the first data, and generate one or more parameter values regarding data compression and/or decompression, the one or more parameter values including a first parameter value, which is a cumulative value of the estimated power consumption in compressing and/or decompressing with respect to the sequence of the first data;
a control circuit configured to generate at least one compression mode information indicating whether or not compression is to be performed, based on the one or more parameter values;
a compressor circuit configured to compress the first data into second data according to the compression mode information; and
a selector circuit configured to output the first data if not compressed or the second data if the first data is compressed, together with the compression mode information.
