Abstract:
1. A micro controller, comprising a CPU, performing processing in accordance with a program, said micro controller further comprising: a memory, storing: grouped compressed codes, resulting from the conversion of original codes into variable length codes in a plurality of compressed code format types, and each type has a fixed length, wherein the plurality of compressed code format types include a first type of a first compressed code length, and a second type of a second compressed code length, an address conversion information, specifying the head address of each group of grouped compressed codes of variable lengths; and a compressed code type information in blocks corresponding to the groups of the compressed codes, including compressed code format type data corresponding to the compressed codes, and indicating the compress code format types of the corresponding compressed codes contained in each group; and a compressed code processing part, specifying, from a code address output by the CPU, an address conversion information and compressed code type information to be referred, and using the specified address conversion information and the compressed code type information to determine the corresponding compressed code address, and reading the corresponding compressed code.
