Abstract :
How to make compilers more useful for developing DSP applications and reduce reliance on assembly coding has long been a topic of interest in the DSP community. This paper presents Siemens solutions for supporting its TriCore DSP/microcontroller architecture, including SIMD instructions, at the C/C++ level. Two solutions based on either extending C/C++ language with the new built-in DSP data types or developing an external DSP class library are investigated. First cut implementations of both methods have achieved 80% coverage of the TriCore instruction set, which is 30 percent higher than the coverage before DSP support was added
