PROBLEM TO BE SOLVED: To provide an apparatus for processing signal which restrains circuit scale from increasing by using a single port memory and has a SIMD (Single Instruction Multiple Data) type processor with simple constitution wherein a variable-magnification function can be built-in at the same time. SOLUTION: The apparatus for processing signal is connected to an external interface for accessing to a register file built-in by a PE (Processing Element) of the SIMD type processor from an outside of the processor, reads a data stored in an image memory, writes/reads the data into/from the PE, is provided with a memory controller to write the data in the memory, and performs a calculation by dividing the data. The memory controller reads the calculated data from the PE except the data of an invalid portion before and after the SIMD processor, writes the data in the memory, returns back an address of data corresponding to the invalid portion by the previous step process, reads the data from the memory, and writes the data into the PE.
