1. A method carried out by a unified shader comprising:
- performing vertex manipulation operations and pixel manipulation operations by transmitting vertex data to a general purpose register block, and performing vertex operations on the vertex data by a processor within the unified shader unless the general purpose register block does not have enough available space therein to store incoming vertex data; and
continuing pixel calculation operations that are to be or are currently being performed by the processor based on instructions maintained in an instruction store until enough registers within the general purpose register block become available.

Abstract
A graphics processing architecture in one example performs vertex manipulation operations and pixel manipulation operations by transmitting vertex data to a general purpose register block, and performing vertex operations on the vertex data b a processor unless the general purpose register block does not have enough available space therein to store incoming vertex data; and continues pixel calculation operations that are to be or are currently being performed the processor based on instructions maintained in an instruction store until enough registers within the general purpose register block become available.

2. A unified shader, comprising:
-
a general purpose register block for maintaining data; a processor unit; a sequencer, coupled to the general purpose register block and the processor unit, the sequencer maintaining instructions operative to cause the processor unit to execute vertex calculation and pixel calculation operations on selected data maintained in the general purpose register block; and wherein the processor unit executes instructions that generate a pixel color in response to selected data from the general purpose register block and generates vertex position and appearance data in response to selected data from the general purpose register block.
