Abstract
In an embodiment, a pipelined digital signal processor (DSP) may generate a valid bit in an alignment stage. The valid bit may be qualified in a decode stage in response to receiving a stall signal and/or a kill signal. The valid bit output from the decode stage may be stored in a latch in an address calculation (AC) stage. The valid bit may be held in the latch by a latch enable circuit in response to receiving a stall signal. The valid bit output from the latch may be qualified in the AC stage. The circuit in the AC stage including the latch, the latch enable circuit, and a valid bit qualifier may be repeated in downstream pipeline stages, for example, the execution stages.
