Abstract

A system and method to perform partial byte writes in a processor circuit is disclosed. The system comprises a bit assembly circuit having a bit assembly register with a corresponding shadow register. Also included is a bit routing circuit configured to transfer at least one data bit from a data bus to a predetermined register position in the bit assembly register and a shadow bit from the data bus to a corresponding register position in the shadow register. The shadow bit indicates that the data bit written comprises valid data. The bit assembly and shadow registers may receive data directly from the data bus as well. Using this circuitry, a partial parallel data block is assembled in the bit assembly register. Thereafter, the partial parallel data block is transferred to a destination register via the data bus with corresponding shadow bits being transmitted to the destination shadow register. The valid data is processed accordingly.
