Abstract: A Multi-I/O SPI for precision converters supports a Dual/Quad/Octal SPI to support the speed requirements for digital transmission and also includes a special mode that can be enabled by hardware and/or software to remove the bit scrambling requirement dictated by the JEDEC standard. The special mode removes the scramble requirement and associates each of the bidirectional data lines to a specific channel. The special mode provides backward compatibility that permits the precision converter to be used with controllers that do not natively support the JEDEC standard. Also, the Multi-I/O SPI includes registers divided into a primary region that is accessed only in default mode at power-up for write and/or read operations, and a secondary region that is accessed by any mode enabled in the control register. By restricting access to the “control” register area to a pre-defined mode in the converter at power-up, the access mode can be controlled.

Abstract: Dynamic and selective compression for content caching is provided for improving content delivery over a digital network. The dynamic and selective compression increased server cache size for higher cache-hit ratios that offset delays associated with compressing and decompressing content. The dynamic compression involves switching between an available set of compression tools in order to compress different files with the compression tool that is optimal for that file. The selective compression involves selectively compressing the content or files with the optimal compression tool when at least a threshold amount of space savings is obtained in an acceptable amount of time. Thus, the caching server caches compressed copies of a first set of files compressed with a first compression tool, compressed copies of a second set of files compressed with a different second compression tool, and an uncompressed third set of files.
