Other Parts Discussed in Thread: SPRC265 , MATHLIB , SPRC542 Windows 7, CGT 7.4.4 (also tried CGT 7.2.6), C64x+, CCSv5.5
I downloaded DSP lib 3.4 from the following directory for the C64x+

Hi,
Thanks for your post.
In general, you can use C64X+ DSPLIB for fixed-point filter computations & C674x DSPLIB for floating point.
For downloads of c64x, c64x+ & c674x DSP LIB, kindly refer the below link:

Ka,
There are multiple ways to optimize the code that you have :
1. DSP compiler based optimization:
the more information you provide regarding your data types and how many times your loops will iterate the better it performs at parallel processing…
Other Parts Discussed in Thread: OMAP-L137 , SPRC090 , SPRC265 , TMS320C6747 , CCSTUDIO , TMS320C6410
I'm developing on OMAP-L137 EVM.
I have to edit EMIFB register. So, I have to include C6747 chip support library.
But I download from below tow…
Hi Miguel,
Thanks for your post.
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_fir_gen_.28FIR_Filter.29
For fixed point computation…
I'm not aware of anyone/group within TI that is working on porting this library to our DSPs. However, since FFTW.org says it is compatible with any platform with a C-compiler, it should work. I would be very surprised if it matched the performance levels…
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…
Hi,
Thanks for your post.
Yes, it is possible to use only DSP stand-alone to run signal processing algorithms which are typically used in computationally intensive real time applications where optimal execution speed of the processor is critical.…
Hi,
Thanks for your post.
Yes, you are right. We do not have double precision functions on c674x but c66x dsplib supports few double precision functions.
As you understood, there are double precision functions supported in C67x DSPLIB and to know…
Hi Yuval,
what should I do now?
You can refer to the applications section in the device Data Manual ( www.ti.com/.../omap-l138.pdf): 1.2 Applications.
I looked at all the guides on the web, but I can't understand what is the right way to work…
