Analyzing data flow graph to detect data for copying from central register file to local register file used in different execution modes in reconfigurable processing array
A reconfigurable array is provided. The reconfigurable array includes a Very Long Instruction Word (VLIW) mode and a Coarse-Grained Array (CGA) mode. When the VLIW mode is converted to the CGA mode, instead of sharing a central register file between the VLIW mode and the CGA mode, live data to be used in the CGA mode is copied from the central register file to local register files.
