Abstract

PURPOSE:To attain the application of an algorithm offering an optimum compression rate among plural compression algorithms and decoding algorithms based on a program data stored in a ROM by using one FPGA. CONSTITUTION:When an applied compression algorithm is designated, a processor 9 reads a program data designating a combination logic from a ROM 10 and sends compression algorithm information to an FPGA 8. The FPGA 8 compresses the compression algorithm information to send the result to a subordinate device 7 and compresses a source data sent from a host device 6 and to send it to the device 7. Upon the receipt of the compression algorithm information to a compression information extract circuit 11, the circuit 11 reads a program data to realize a decoding algorithm corresponding to the compression algorithm designated thereby from the ROM 10 and allows the FPGA 8 to decode and send the compression data sent from the device 7. Thus, the application of an algorithm offering an optimum compression rate depending on the data characteristic is attained.
