Abstract
A system and method for interfacing graphics program modules written to execute on a plurality of functional units of a graphics processor using a shared memory. A central processing unit (CPU) receives a first graphics program module that outputs a first parameter referenced by a first graphics program module identifier, a second graphics program module that inputs the first parameter by referencing the first graphics program module identifier, and a first data structure that includes, in a pre-defined order, a list of first data structure identifiers. The CPU identifies a memory location in the shared memory, based on the pre-defined order of the first data structure identifiers, for one of the first data structure identifiers that is the same as the first graphics program module identifier. The CPU modifies the first and second graphics program modules to reference the first parameter by the identified memory location in the shared memory.
