similar to: How can I optimize speex under SH

Hello! I'v downloaded speex lib 1.1.11.1. I am trying to port speex lib to Blackfin processor. I am using VisualDSP++ 4.0. If I am compiling source codes with using floating point everything ok. When I am compiling with FIXED_POINT defined everything's ok and code works about two times faster. But when I am defining BFIN_ASM I am getting several compiling errors in Blackfin assembler

I am studying the speex 1.0.5 C source code ,but i feel it is hard to understand the code ,especially the ltp.c and filters.c file. may you tell me the detail algorithm or the more detail notation of the source code of this two file.including below functions void open_loop_nbest_pitch(float *sw, int start, int end, int len, int *pitch, float *gain, int N, char *stack); float

Hi, I'm trying to get speex working on an ARM board (ARM926EJ-Sid(wb) core, ARM 5TE architecture) and getting segfaults if build with "--enable-fixed-point --enable-arm5e-asm" options. If I use just "--enable-fixed-point", then it runs fine, but once I add "--enable-arm5e-asm" it start crashing (I use testenc to test it). Further investigation showed, that it

Kemal, It sounds like you are doing something wrong. I strongly recommend that you profile your application to see exactly where the CPU time is being spent. AMD happens to have a nice profiler called CodeAnalyst that they give away for free. And it's plenty usable on Intel CPUs as well. http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_3604,00.html Make sure you test a

Hi! I have some questions about that functions: fir_mem16, iir_mem16 and filter_mem16. Filtering is very slow on TI DSP, and i want to optimise it. Can somebody give me formulas which discribe work of this filters? Or any suggestions about how to transform code for better performance. I going to implement this functions in assembler, but it is hard to do without full understanding how functions

hello i am a new user for this group. i am working at a ISP. here i want to made a bridge firewall i am using fedora core 3. i want to block a serirs of ip address 192.16.18.0/255.255.255.0 and want to give the accesss only 172.16.18.0/255.255.255.0. but iptables not be able to block ip;s its passes all the ip series. i made my machine as bridge. i think my bridge passes all the

I have used the patch to build opus 1.1. Although I have not tried the latest git master, will try that. Will that work for armv7, armv7s and arm64?

Hello Guys, I am having some problems with configuring SAMBA with regards to performance. We are running SAMBA 2.2.3a on Dual PIII 1Ghz machines with 512MB of RAM. The server is running on a default server installation of Red Hat 7.2. We have a 500Gb RAID 5 drive using the Promise SX6000 Raid controller. Currently we are only getting a throughput of ~5MB/S for writes and ~13MB/S for reads.

Hi, I am trying to get the alias info for the following code. The alias analysis returns "MayAlias" for arrays "A" and "B" in both the functions instead of "NoAlias". What passes should I run in opt before the alias analysis pass to get the accurate result? Example: //Note: static and called by func() only. static int sum(int *A, int *B) { int i = 0,

Hi! It seems that using a different compiler (I assume the development is done with MSC) uncovers various issues with the floating point. Here is the second one I'm seeing - DOMAIN error from sqrt(). In the open_loop_nbest_pitch(), this line: g = DIV32(corr[i-start], 10+SHR32(MULT16_16(spx_sqrt(e0),spx_sqrt(energy[i-start]) ),6)); The values are: e0 is 7.2 i is 142, start is 17

Can anyone tell me why the size of st is defined as: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); Reference: nb_encode_init function. Specifically, I would like to know why 8000 floats are allocated? Thanks and regards, Vinay -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, im looking to build a page similar to a shopping cart page. When you change the ''price'' or ''quantity'' fields, the total is calculated and displayed. There are other fields in the form which have no relation to this action. So i guess observe_form is not required. Can someone tell me what the best practise is for this?

I have found that filter_mem2 fixed point does not match the inlined assembly version for arm4. Looking closer there appears to be an off by one error. It occurs when setting the value of mem at the end of the inner loop. In the C fixed point version this is done with a subtract. In the arm4 version instead of multiplying den by yi, it is multipled by nyi and then an add is done. This
