A data conversion apparatus and a data conversion method are disclosed by which, when data of a format used in a processing apparatus is to be written into a memory, it can be written in a compressed form and, when the data is to be read out from the memory, it can be read out in a decompressed form. An address conversion section converts an address from the processing apparatus side from an address of a floating-point data space into an address of a fixed-point data space. A data compression section converts data of a floating-point format from the processing apparatus side into data of a fixed-point format. A data decompression section converts data of the fixed-point format from the memory side into data of the floating-point format. A predetermined portion of the address is utilized, upon the data conversion, as an exponent part of the data of the fixed-point format. |
