microblaze fxmul Options

[nelson]

hello, I have followed the Complex_Fir_MB tutorial to implement a FIR filter using fixed point, my target board is an Spartan Starter 3e Rev D.
After building project, to import the application software. EDK give me this error: undefined reference to `FXMUL32'

Because that,I have defined in my Sw file
#define FXMUL32(a,b,DW) ((int32)(((((int64)((int32)(a))*(int64)((int32)())+((int64)1<<((DW)-1)))>>DW))
this is the definition from co_math.h file . Also include co_math and co_types in SW.
Then EDK give me :

In function 'software_fir' 'int64' undeclared (first use in this function)(Each undeclared identifier is reported only once for each function it appears in.)expected ')' before numeric constant.

Later, I use this definition and no error returned:
#define FXMUL32(a,b,DW) ((int32)((((((int32)(a))*((int32)())+(1<<((DW)-1)))>>DW)))
I'm only using the co_int32 type, Is it a correct operation?

Regards

Hi Jorge,

MicroBlaze is a 32-bit system, so the type int64 is not supported, and the FXMUL32 cannot be used here. If you just change the type to int32 as the result of 32-bit multiplication, however, important data will get lost, and the result you get won't be correct.

Here is a simple function, which splits FXMUL32 into a few FXMUL16's. You can use this function to do the job of FXMUL32 in MicroBlaze.

CODE

int32 fxmul32(int32 a, int32 b)
{
    int16 al, ah, bl, bh;
    int16 r1, r2, r3;
    
    al = a & 0xff;
    ah = (a >> 16) & 0xff;
    bl = b & 0xff;
    bh = (b >> 16) & 0xff;
    
    r1 = FXMUL16(ah, bh, FRACBITS-16);
    r2 = FXMUL16(ah, bl, FRACBITS-16);
    r3 = FXMUL16(al, bh, FRACBITS-16);
    
    return (((int16)r1 << 16) + (int16)r2 + (int16)r3);
}

Hope this helps.

Regards,

Mei

Hello Mei,
Thanks for the fxmul code.

Finished the tutorial, I don't receive anything from RS232 DTE port to hyperterminal.
I also send my project files to support@ImpulseAccelerated.com.

Regards

Jorge.

Hi, same problem here. I finished a design but had no response from RS232 port.

Any help would be greatly appreciated.

Hi Nelson,

Sorry for the late response. I didn't receive your code in last November. Could you please resend the EDK project files to support@impulsec.com?

Thanks,

Meix
