A device includes an M-bit input request for service bus, a MASKGEN component that generates a shifting mask, the MASK component that generates an 2*M-bit enabled request for service bus, a NEGATE component that may perform a negation operation on the MASK 2*M-bit enabled request for service output, and a COMBINE component which receives the MASK 2*M-bit enabled request for service output and 2*M-bit NEGATE output and combines them into M-bit 1-HOT grant output bus. The COMBINE output indicates which request for service is being granted by the device.
