Latest Patents
One of his latest patents is titled "Programmatic access to the widest mode floating-point arithmetic supported by a processor." This invention introduces a software mechanism that allows programmers to embed selected machine instructions into program source code conveniently. It also restricts the re-ordering of these instructions by the compiler without requiring significant modifications to the compiler's processing. The mechanism utilizes a table-driven approach to parse embedded machine instruction constructs, ensuring syntax and semantic correctness. It translates these constructs into low-level compiler internal representations, which can be integrated into other compiler code with minimal changes. This innovation enhances run-time application performance by enabling library routines containing embedded machine instructions to be optimized effectively.
Another notable patent is "Method and apparatus for ordered predicate phi in static single assignment form." This invention provides a mechanism for static single assignment in the presence of predicated code. It employs guards on each source operand of the phi function to indicate the conditions under which the corresponding source operand is live. This ensures the correct materialization of phi functions after code reordering. The invention maintains the order of operands through subsequent code transformations, allowing for efficient execution in a straight line of code.
