RECONFIGUABLE PROCESSOR, APPARATUS AND METHOD FOR CONVERTING CODE THEREOF

摘要

PURPOSE: A reconfigurable processor, a code conversion apparatus VLIW, and a method thereof are provided to selectively map a code area where does not apply software pipelining to a VLIW mode or a CGA mode according to degree of parallelism. CONSTITUTION: A processing unit(101) includes a VLIW(Very Long Instruction Word) and a CGA(Coarse-Grained Array) mode. A controlling unit(103) detects a target region from a code which is executable from the processing unit. The controlling unit maps the detected target area to the VLIW mode or the CGA mode according to the schedule length of the detected target area. The target area is defined as a part which does not apply software pipelining in the code.
