54 results about "Intrinsic function" patented technology

In computer software, in compiler theory, an intrinsic function (or builtin function) is a function (subroutine) available for use in a given programming language whose implementation is handled specially by the compiler. Typically, it may substitute a sequence of automatically generated instructions for the original function call, similar to an inline function. Unlike an inline function, the compiler has an intimate knowledge of an intrinsic function and can thus better integrate and optimize it for a given situation.

System and methodology for determining layout-dependent effects in ulsi simulation

A layout of a semiconductor circuit is analyzed to calculate layout-dependant parameters that can include a mobility shift and a threshold voltage shift. Layout-dependant effects that affect the layout dependant parameters may include stress effects, rapid thermal anneal (RTA) effects, and lithographic effects. Intrinsic functions that do not reflect the layout-dependant effects are calculated, followed by calculation of scaling modifiers based on the layout-dependant parameters. A model output function that reflects the layout-dependant effects is obtained by multiplication of each of the intrinsic functions with a corresponding scaling parameter.

The “kill” intrinsic may be used with DMA operations. Data objects being DMA'ed from a local store of a processor may be “killed” through use of the “kill” intrinsic prior to submitting the DMA request. Data objects being DMA'ed to the local store of the processor may be “killed” after verifying the transfer completes.
