dsplib_c674x_3_2_0_1 FFT_Example_674_LE_COFF fails to compile

When attempted to compile the FFT_Example_674_LE_COFF from dsplib_c674x_3_2_0_1, the compilation failed with the error:

**** Clean-only build of configuration Debug for project FFT_Example_674_LE_COFF ****

gmake: *** No rule to make target `clean'.

The #error is being generated in the dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm/DSPF_sp_mat_mul_gemm.h header, which is been written such DSPF_sp_mat_mul_gemm isn't support for a TMS320C6740 target:

#if defined(_TMS320C6600)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm/c66/DSPF_sp_mat_mul_gemm.h>
#else
#error invalid target
#endif


Looking at the dsplib_c674x_3_2_0_1 installation, there a DSPF_sp_mat_mul_gemm.h does appear in a c674 directory. Therefore, changed the dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm/DSPF_sp_mat_mul_gemm.h to:

#if defined(_TMS320C6600)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm/c66/DSPF_sp_mat_mul_gemm.h>
#elif defined(_TMS320C6740)
#include <ti/dsplib/src/DSPF_sp_mat_mul_gemm/c674/DSPF_sp_mat_mul_gemm.h>
#else
#error invalid target
#endif

The same issue exists in:

- dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm_cplx/DSPF_sp_mat_mul_gemm_cplx.h

- dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSP_fir_r8_h16/DSP_fir_r8_h16.h

- dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSP_fir_r8_h24/DSP_fir_r8_h24.h

- dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSP_fir_r8_h8/DSP_fir_r8_h8.h

Are the DSPF_sp_mat_mul_gemm, DSPF_sp_mat_mul_gemm_cplx, DSP_fir_r8_h16, DSP_fir_r8_h24 and DSP_fir_r8_h8 functions supported on a c674x device?

    Hi,

    Are the DSPF_sp_mat_mul_gemm, DSPF_sp_mat_mul_gemm_cplx, DSP_fir_r8_h16, DSP_fir_r8_h24 and DSP_fir_r8_h8 functions supported on a c674x device?

    In my understanding, Of course  It won't give any problem.

    Please refer the following ti e2e which is related to your problem.

    Thanks for the confirmation.

    Should the include files in dsplib_c674x_3_2_0_1 be "fixed" so that the FFT_Example_674_LE_COFF example compiles without error?

    Hi Chester,

    Thanks for your post.

    Actually, the specified functions posted by you, DSPF_sp_mat_mul_gemm, DSPF_sp_mat_mul_gemm_cplx, DSP_fir_r8_h16, DSP_fir_r8_h24 and DSP_fir_r8_h8 are supported in C674xCPUCycleAccurateSimulator which are tested and benchmarked. Kindly check the below link for the test results:

    http://software-dl.ti.com/sdoemb/sdoemb_public_sw/dsplib/latest//exports/DSPLib_c674xTest_Report.html

    For C674x device, please check the supported kernel functions for C674x DSP_LIB from the below wiki:

    http://processors.wiki.ti.com/index.php/C674x_DSPLIB#DSPF_sp_mat_mul_.28Matrix_Multiply.29

    For fixed point computation, the C674x core is fully compatible with the C64x+ DSPLIB, kindly check the c64x+ DSP library programmer's reference as below:

    http://www.ti.com/lit/ug/sprueb8b/sprueb8b.pdf (please check Table 3 -4 & Table 3 -5)

    For downloads of c66x, c67x, c64x, c64x+ & c674x DSP LIB, kindly refer the below link:

    http://www.ti.com/tool/sprc265

    Thanks & regards,

    Sivaraj K

    Hi,

    I am able to build "FFT_Example_674_LE_COFF" DSP lib project from "dsplib_c674x_3_1_1_1"

    Did you change anything in CCS project?

    I am also able to build FFT_Example_674_LE_COFF from dsplib_c674x_3_1_1_1.

    However, it is the FFT_Example_674_LE_COFF from the later dsplib_c674x_3_2_0_1 that I was unable to build.

    Titusrathinaraj Stalin said:

    No, I imported the unmodified FFT_Example_674_LE_COFF from the later dsplib_c674x_3_2_0_1 into CCSv6 and got the compile errors in my initial post.

    Hi Chester,

    Now, I'm able to build "FFT_Example_674_LE_COFF" DSP lib project from "dsplib_c674x_3_2_0_1"


    Chester :

    Are the DSPF_sp_mat_mul_gemm, DSPF_sp_mat_mul_gemm_cplx, DSP_fir_r8_h16, DSP_fir_r8_h24 and DSP_fir_r8_h8 functions supported on a c674x device?

    Titus :

    In my understanding, Of course  It won't give any problem.

    Sorry for the wrong information,

    Actually, Yes, It could be the "*.h" files supported to other target (may be c66x) and not for c674x.

    I have done workaround to build in which i have changed the following "*.h" files from "c674" folder.

    DSPF_sp_mat_mul_gemm.h
    DSPF_sp_mat_mul_gemm_cplx.h
    DSP_fir_r8_h16.h
    DSP_fir_r8_h24.h
    DSP_fir_r8_h8.h


    Ex:

    Backup the "DSP_fir_r8_h8.h" file from the below directory and copy the "DSP_fir_r8_h8.h" file from "c674" folder to the below directory again.

    ti/dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm

    Workaround

    Copy the "ti/dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm/c674/DSPF_sp_mat_mul_gemm.h" to  "ti/dsplib_c674x_3_2_0_1/packages/ti/dsplib/src/DSPF_sp_mat_mul_gemm/DSPF_sp_mat_mul_gemm.h"

    Output build logs:
