Abstract: A statistically lossless transform (SLT) can be used with data (e.g., image data) to be compressed. Prior to compression, an SLT stabilizes the variance for a read noise+Poisson process. The SLT redistributes (image) data that has been quantized with a linear uniform quantizer and essentially assures there are no gaps in the output values (i.e., all output digital values are used). The SLT re-quantizes the data with a quantization interval width that is proportional to the standard deviation of the process.

Abstract: Methods and systems are provided for a programmable parallel computation and data manipulation accelerator that may be used, for example, in cryptographic calculations. They allow acceleration of a broad variety of cryptographic algorithms and/or portions of algorithms, and are not algorithm specific. This system comprises a butterfly and inverse butterfly multiplexing permuter network and a lookup table. This system may allow replication of input registers, “expansion,” so that an individual bit may be used in multiple calculations in parallel, accelerating completion of the cryptographic algorithm. The system may allow “diffusion” of the expanded bits through the system's butterfly and inverse butterfly network, and may provide for “confusion” of the resulting bits through the system's lookup table. In some implementations, the system may allow completion of a computation within an algorithm within one clock cycle.
