CONVERTER AND CONVERSION METHOD

Document Type and Number:

Japanese Patent JP2012088909

Kind Code:

A

Abstract:

To provide a converter and a conversion method for reducing a memory access.

A converter includes: a storage part for storing a register type byte code fetched from a memory; a first storage part for storing the template of a native code corresponding to the instruction code of the byte code; an instruction creation part for extracting the byte code from the storage part, and for creating one or more native codes corresponding to the byte code by using the template of the native code stored in the first storage part; and a second storage part for storing data showing a correspondence relation between a physical register and a register on the memory for storing the data corresponding to the data stored in the physical register based on the native code created by the instruction creation part. The instruction creation part omits the creation of the native code when it is determined that the created native code is a load instruction relating to the register on the memory included in the data stored in the second storage part.
