C66x standard C compiler intrinsic functionsΒΆ

The OpenCL C compiler for the C66x DSP supports the C66x standard C compiler set of intrinsic functions, with the exception of those intrinsics that accept or result in a 40 bit value.

Please refer to the subsection 7.5.5. Using Intrinsics to Access Assembly Language Statements in the C6000 Compiler User’s Guide for a description of these intrinsic functions.

Important

The prototypes for the intrinsics may be different in OpenCL C code than the prototypes in standard C code. The C6000 Compiler User’s Guide documents the standard C code prototype. The OpenCL C prototypes are listed below.

The majority of the changes involve the long long type in standard C code and the long type in OpenCL C code. The long long type in standard C code is a 64 bit type whereas the OpenCL C code equivalent is the long type.
