Abstract
An instruction cache and data cache used to virtualize the storage of global data and instructions used by graphics shaders. Present day hardware design stores the global data and instructions used by the shaders in a fixed amount of registers or writable control store (WCS). However, this traditional approach limits the size and the complexity of the shaders that can be supported. By virtualizing the storage of the global data and instructions, the amount of global or state memory available to the shader and the length of the shading programs are no longer constrained by the physical on-chip memory.
