3. The method of claim 1 , wherein the sending changes the set of compression parameters for the packet-of input data.
1. A method to control compression of data for transmission over a serial data link, the method comprising: adjusting, at a parameter estimation processor, a target compression ratio by a first compression ratio to determine a remaining compression ratio, wherein the first compression ratio was performed by a resampling operation; estimating, at the parameter estimation processor, a set of compression parameters that are used to achieve the remaining compression ratio, the set of compression parameters includes N attenuation values, a filter order and a type of encoding; and sending the set of compression parameters to a data sample compressor, the data sample compressor applies the compression parameters to a packet of input data and outputs a plurality of compressed data words, and wherein an attenuator of the data sample compressor divides the packet of input data into N segments and applies an attenuation value from the set of N attenuation values to the data samples in one of the N segments.
