Register Set

The instruction operands are contained in either the current set of 32 64-bit registers in the integer register file or the set of 32 64-bit registers in the floating point register file. Instruction operands in the floating point register file can refer to single or double-precision registers. Pixels are typically contained in single-precision registers. In addition to the two register files, VIS instructions use the Graphics Status Register (GSR). GSR is used for conversion between formats and for memory alignment.
