Hi,
I am using C5515. It has an Hardware FFT Accelarator.
I got the hwafft_rom.asm, hwafft.asm and hwafft.h
I used a sample code given in TI documentation for FFT implementation.
But, I am not able to link .asm files to the project.
I feel .asm files will be converted to .obj after building. But, I cant see any of my .asm files being converted to .obj
Maybe because of this I am getting a [E0000]: Parse error when i buidl
Can u plz help me out
Thankx for the reply.
I had those issues. But I just played arround with the files and somehow came out of it. Now, I dont have any errors ( except four warnings).
But, when i am running the code, I am not able to get the FFT computed. As soon as the code reaches the FFT computation part, it just stands still.
So , I stopped the running to see what is getting executed. The code gets stuck here
8e49bdeb1110 COPR #16,AC0,dbl(*AR2-),AC1 :: MOV AC1,dbl(*(AR3+T0))
8e49bdeb1110 COPR #16,AC0,dbl(*AR2-),AC1 :: MOV AC1,dbl(*(AR3+T0))
8e49bdeb1110 COPR #16,AC0,dbl(*AR2-),AC1 :: MOV AC1,dbl(*(AR3+T0))
8e49bdeb1110 COPR #16,AC0,dbl(*AR2-),AC1 :: MOV AC1,dbl(*(AR3+T0))
I am not sure , what exactly these statements does. But all the lines are same !!
If i step debug this, it loops arround these lines.
But, If i give a run and stop , it get stuck @
040009 BCC #0x3d12c3,AC0 == #0
and if I give a run again : I get an error message saying I cant do tht !!!!!!
I am struggling with this issue for the past 2-3 days. It will be a great help, If you can tell me how to solve this.
I have a breif code structure, which shows how I am computing FFT. Please have a look.
This is my code

I have defined the below code in an assembly file. I got this code snippet from TI forum. I was asked to use this since I am using large memory model. It seems
FFT accelerator supports only small memory model
.sect ".onchip_code"
.def _hwafft_wrapper
; HWAFFT code burned in C5515 ROM seems to support small memory model only.
; The following wrapper helps to use HWAFFT for large/huge memory models.
; CVN 20110920
_hwafft_wrapper:
XAR2 = XAR1
XAR3 = XAR0
call AC0
return
I have defined the below code in a C header file.(USBSTK5515.h)
typedef Uint16 (*hwafft_func_t)(Int32 *data,
Int32 *scratch,
Uint16 fft_flag,
Uint16 scale_flag);
Uint16 hwafft_wrapper( Int32 *data,
Int32 *scratch,
Uint16 fft_flag,
Uint16 scale_flag,
hwafft_func_t fft_func);
