Abstract:
A graphics system for storing display list values in a register file, wherein the display list is shortened to enable fast processing time while maintaining the quality of information contained in the display list, the graphics system comprising:a register file, for storing at least one set of parameter values, the register file comprising a plurality of registers;a load instruction unit, for storing an instruction having an opcode portion that specifies a rendering operation, and a write-enable portion that spans a plurality of bits, wherein a first bit corresponds to a target starting register file address and subsequent bits sequentially correspond to register file addresses that follow the target starting register file address;a shifter coupled to receive the write-enable portion, wherein the shifter sequentially performs single-bit shifts upon the contents of the write-enable portion; anda rendering parameter storage controller coupled to the shifter and the register file, wherein the rendering parameter storage controller sequentially steps through register file addresses as write-enable portion bits are considered by the shifter, and stores a display list value in the register file in response to a write-enable portion bit under consideration by the shifter having a predetermined value.
