Abstract: To reduce inter- and intra-instruction register bank access conflicts in parallel processors, a processing system includes a remapping circuit to dynamically remap virtual registers to physical registers of a parallel processor during execution of a wavefront. The remapping circuit remaps virtual registers to physical registers at a register mapping table that holds the current set of virtual to physical register mappings based on a list of available registers indicating which physical registers are available for a new mapping and a register mapping policy.
