dsPIC - Calling asm code from C

[drZoidberg]

Hi! I'm a student trying to learn digital filters, and i have a problem with c being too slow.

I use a dsPIC30F4011, and i want to use the hardware multiplier. But I dont know how to call assembler code from c.

Can someone please show me how to call asm from c?

Thanks!

Hi

Just add the asm() tags and you're ready to go!

Code: [Select]

asm("TBLRDL [W0], W4");

Assuming you are using the MicroChip C compiler, then read chapter 9 of the manual.
