PURPOSE:To improve the compression and decoding processing speed for the entire device. CONSTITUTION:The data compression decoding device is made up of a data compression circuit consisting of an intermediate data conversion means 1, a coding means 2, and a buffer memory B1, and up of a data decoding circuit consisting of a decoding means 3, an intermediate data inverse conversion means 4 and a buffer memory B2. The intermediate data conversion means 1 in the data compression circuit converts input data into intermediate data and stores the data tentatively into the buffer memory B1. The coding means 2 codes the intermediate data stored in the buffer memory B1 into an output code. The decoding means 3 in the data decoding circuit converts the input code into intermediate data and stores the data tentatively to the buffer memory B2. The intermediate data inverse conversion means 4 inverts the intermediate data stored in the buffer memory B2 into output data. |
