Abstract

Compression and decompression of numerical data can apply to floating-point or integer samples. Floating-point samples are converted to integer samples and the integer samples are compressed and encoded to produce compressed data for compressed data packets. For decompression, the compressed data retrieved from compressed data packets are decompressed to produce decompressed integer samples. The decompressed integer samples may be converted to reconstruct floating-point samples. Adaptive architectures can be applied for integer compression and decompression using one or two FIFO buffers and one or two configurable adder/subtractors. Various parameters can adapt the operations of adaptive architectures as appropriate for different data characteristics. The parameters can be encoded for the compressed data packet. This abstract does not limit the scope of the invention as described in the claims.

First claim

I claim:

1. A method for transfer of floating-point data across a data transfer interface connecting components of a computer system, comprising:
scaling a plurality of floating-point samples by a scale factor that is inversely proportional to a maximum floating-point value for a set of input floating-point samples, wherein each floating-point sample comprises an original number of bits in accordance with a floating-point format used in the computer system, the floating-point form…
