Abstract: 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.

Abstract: 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.

Abstract translation: 一种数据缓冲/变换系统和方法，其压缩接收到的信号并将压缩的接收数据信号存储在数据存储单元中以节省存储使用。 系统在发送信号之前解压缩数据信号。 所接收的数据信号可以是编码数据信号。 在这种情况下，系统进一步对接收的数据信号进行解压缩，对信号进行解码，重新压缩信号，并将该信号存储在数据存储单元中。 该系统和方法采用组合压缩器和第一解压缩器和第二解压缩器，因此系统和方法可以同时解压缩压缩的接收数据信号并对压缩的解码的接收数据信号进行解压缩。
