  • Forum Post: Accessing DNUM on a 6472

    Peter Robertson
    I am using v6.1.12 of the compiler (I assume that number also applies to the assembler) and it refuses to accept DNUM as a register. I am building with the -mv=6472 option which it accepts without comment, so it should understand the processor. cl6x -mv=6472 .\x.asm ".\x.asm", ERROR...

    The explanation is understood. However, here are the following reasons to prefer this behavior fixed in the Assembler. First, having structures and functions with same name is prettly legal C, and one would expect that assembling would produce a warning and/or reduce the declarations to nops, but not...

    You're wrong, sizeof returns a size_t. Which (for the c5500) is defined as unsigned int. Besides the compiler bug is still valid. memset also use size_t (I think it does, I am not sure, it does not complain when feeding > 32767). And yes you can create an array larger then 32767, even larger...

    Hi, We're using 2 different DSPs, a C6455 and a C6747. On the C6455 we have some pixel processing loops and selecting --no_bad_aliases makes a big difference to how fast these loops run (possibly better than 10x improvement). Obviously we need to follow the guidance in the manual about when...

    The C6000 compiler (I'm using v6.1.15) provides the time.h functions like clock(), strftime(), etc. That's good, but on an embedded system they won't have the proper time when the system powers up, and I don't see any way of initializing the time and date. Is there a method of initializing...
