TMS320F280049C: Does CLA support fixed-point calculation

Rayna,

The compiler limitations are listed in the C2000 Compiler Guide ( http://www.ti.com/lit/spru514 ). Refer to the CLA compiler section of the guide.  Specifically C Language Implementation and CLA Language Restrictions.

Fixed point is supported, but due to the architecture of the CLA, it is going to be poor performance compared to the C28x. Most of the CLA opcodes are floating point instructions, with a few to do integer math (ADD, SUB, CMP, LSL, LSR); the architecture does not have an integer multiply instruction.

Also refer to the CLA Software Development Guide.  Specifically section 6 - Comparison to C28x+FPU
