发明名称 DATA RESTORATION CIRCUIT
摘要 PURPOSE:To provide a data restoration circuit for restoring compressed data at a high speed. CONSTITUTION:A compressed data expansion circuit is provided with a control circuit 12 for outputting the various kinds of control signals for the expansion processing of the compressed data, an address pointer 9 for inputting compressed data signals and their address signals, responding to expansion starting/stopping signals from the control circuit 12 and counting address values, a selector 10 for inputting the address signals and output signals from the address pointer 9, performing changeover corresponding to selector switching signals from the control circuit 12 and outputting one of them, a memory 11 for tentatively storing the compressed data with the compressed data signals as data input and with the output signals of the selector 10 as address input and a data address generation circuit 13 for responding to data fetching signals from control circuit 12, fetching and decoding control data within the compressed data from the memory 11 and generating write signals and the data address of accompanying data read from the memory 11 as hardwares.
