A page generation system that efficiently generates a page segment by clearing memory immediately after data representing the page segment is read from memory. The system generates a page in memory by writing the data representing the image content of the page to a memory block. The memory block is initially clear (all logical 0's) to enable the system to efficiently generate the page segment by writing the positive content of the page segment without having to write the blank sections of the page segment. By clearing memory immediately after data is read from memory, the page generator does not need to zero clear a memory block prior to constructing a page segment therein.

ALDC with zero clear after read

A data buffering/transformation system and method that compresses a received signal and stores the compressed received data signal in a data storage unit to conserve storage usage. The system decompresses the data signal prior to transmitting the signal. The received data signal may be an encoded data signal. In such a case, the system further decompresses the received data signal, decodes the signal, recompresses the signal, and stores the signal in the data storage unit. The system and method employs a combination compressor and first decompressor and a second decompressor so the system and method can simultaneously decompress a compressed received data signal and decompress a compressed decoded received data signal.
