An apparatus is disclosed. The apparatus comprises an instruction mapping table, which includes a plurality of instruction counts and a plurality of instruction pointers each corresponding with one of the instruction counts. Each instruction pointer identifies a next instruction for execution. Further, each instruction count specifies a number of instructions to execute beginning with the next instruction. The apparatus also has a data operation unit adapted to receive a data group and adapted to execute on the received data group the number of instructions specified by a current instruction count of the instruction mapping table beginning with the next instruction identified by a current instruction pointer of the instruction mapping table before proceeding with another data group.

An arithmetic logic stage in a graphics processor unit pipeline includes a number of arithmetic logic units (ALUs) and at least one buffer that stores pixel data for a group of pixels. Each clock cycle, the buffer stores one row of a series of rows of pixel data. A deserializer deserializes the rows of pixel data before the pixel data is placed in the buffer. After the buffer accumulates all rows of pixel data for a pixel, then the pixel data for the pixel can be operated on by the ALUs.

An arithmetic logic stage in a graphics processor unit includes arithmetic logic units (ALUs) and global registers. The registers contain global values for a group of pixels. Global values may be read from any of the registers, regardless of which of the pixels is being operated on by the ALUs. However, when writing results of the ALU operations, only some of the global registers are candidates to be written to, depending on the pixel number. Accordingly, overwriting of data is prevented.

Sourcing immediate values from a very long instruction word includes determining if a VLIW sub-instruction expansion condition exists. If the sub-instruction expansion condition exists, operation of a portion of a first arithmetic logic unit component is minimized. In addition, a part of a second arithmetic logic unit component is expanded by utilizing a block of a very long instruction word, which is normally utilized by the first arithmetic logic unit component, for the second arithmetic logic unit component if the sub-instruction expansion condition exists.

An arithmetic logic stage in a graphics pipeline includes a number of arithmetic logic units (ALUs). The ALUs each include, for example, a multiplier and an adder. The ALUs are interconnected by circuitry that, for example, routes the output from the multiplier in one ALU to both the adder in that ALU and an adder in another ALU.

A method for performing image rendering. The method includes identifying a tile in an image, wherein the image comprises a plurality of tiles including color data that is displayed by a plurality of pixels. A quantized first base value and a quantized second base value are accessed from a block of memory, wherein the block is associated with the tile. Reverse quantization is performed on the quantized first and second base values to obtain a reproduced first base value, and a reproduced second base value corresponding to the tile for purposes of determining color values for corresponding pixels.
摘要:
An arithmetic logic stage in a graphics processor unit includes a number of arithmetic logic units (ALUs). An instruction is applied to sets of operands comprising pixel data associated with different pixels. The value of a conditional execute bit determines how the pixel data in a set of operands is processed by the ALUs.
