    • A reconfigurable digital signal processing system comprises a serial to parallel converter comprising at least one delay block and at least one decimation block arranged to convert, in use, a first serial signal with a first sampling rate to a multiplicity of parallel subband signals with a second sampling rate, wherein the second sampling rate is less than or equal to the first sampling rate. Processing blocks are arranged, in use, to process the subband signals to produce processed signals. A configuration controller is arranged to modify, in use, the decimation factor of each decimation block and to load, in use, a configuration into the memory of a processing block. A parallel to serial converter comprising at least one expansion block, the parallel to serial converter arranged to recover from the processed signals, in use, a second serial signal with a sampling rate substantially equal to the first sampling rate. In use, in normal run-time operation the decimation factor of each decimation block is equal to the number of subband signals and when, in use, run-time reconfiguration is required the configuration controller is arranged to decrease the decimation factor so that the second sampling rate increases; load the configuration into the memory of a processing block; and increase the decimation factor to again be equal to the number of subband signals.
    • 可重构数字信号处理系统包括串行到并行转换器,其包括至少一个延迟块和至少一个抽取块,该至少一个抽取块被布置为在第一采样率下将具有第一采样率的第一串行信号转换成多个并行子带信号, 采样率,其中第二采样率小于或等于第一采样率。 处理块在使用中被布置为处理子带信号以产生经处理的信号。 配置控制器被布置为在使用中修改每个抽取块的抽取因子并且在使用中将配置加载到处理块的存储器中。 一种并行串行转换器,包括至少一个扩展块,所述并行到串行转换器被布置成在使用中从处理的信号中恢复具有基本上等于第一采样率的采样率的第二串行信号。 在使用中,在正常的运行时操作中,每个抽取块的抽取因子等于子带信号的数量,并且在使用中需要运行时重新配置时,配置控制器被设置为减少抽取因子,使得第二 抽样率提高; 将配置加载到处理块的存储器中; 并且将抽取因子增加到再次等于子带信号的数量。
