摘要
One embodiment of the present invention sets forth a technique for allocating register file entries included in a register file to a thread group. A request to allocate a number of register file entries to the thread group is received. A required number of mapping table entries included in a register file mapping table (RFMT) is determined based on the request, where each mapping table entry included in the RFMT is associated with a different plurality of register file entries included in the register file. The RFMT is parsed to locate an available mapping table entry in the RFMT for each of the required mapping table entries. For each available mapping table entry, a register file pointer is associated with an address that corresponds to a first register file entry in the plurality of register file entries associated with the available mapping table entry.
