Abstract: The present invention includes a data compression system which implements transformation and quantization functions using analog devites. The system includes a transformation module with analog devices (22), a quantization module with analog devices (24) and an entropy coding module (26). A data decompression system which implements inverse transformation and inverse quantization functions using analog devices is also shown.

Abstract: A circuit for ensuring stabilized configuration information upon power-up is disclosed. In one embodiment, a semiconductor device includes a configuration information stored in a number of nonvolatile storage elements (fuse bits (16)). A configuration power-on reset circuit (10) generates a signal for latching the configuration data into volatile configuration registers (18) on power-up. The configuration data signals are generated in response to a power-on reset (POR) pulse, and not latched until a predetermined delay after the POR pulse is terminated. The predetermined delay allows time for the data signals from the fuse bits (16) to “settle.” Subsequent POR pulses will not result in another latching action.
