Patent ID: 7521621

Claim:
A waveform storage processing apparatus comprising: a storage section having a storage area specified with a plurality of addresses each having a data width of n bits; a segmentation section that segments input waveform data into a plurality of frames; a compression section that, for each of the frames, performs a compression process on the waveform data to thereby generate compressed waveform data of m divided by bits; an auxiliary information generation section that, for each of the frames, generates auxiliary information including compression information indicative of a form of the compression process performed on the frame; a to-be-written data formation section that, for each of the frames, forms a predetermined number j of to-be-written data of n bits on the basis of data of m bits formed by retrieving samples of the compressed waveform data, k samples at a time, and data of n−m bits from of the auxiliary information of a next frame; and a writing section that sequentially writes the j to-be-written data, formed for each of the frames, to the storage area specified with the predetermined number j of successive addresses of said storage section.
