hi I have a source code of compression vidéo (h.264 ,jpeg) how is exécutable in visual studio c++,my problem is how to implement this code in NiosII ,how to convert this source code in niosII. thanks in advance.

sounds like you have a lot of work to know. first of all. can you compile simple C-code in NiosII?(Eclipse) I mean have you done it? and then. have you tried to compile your code in NiosII?

hi akira,thank you for your answer ,yes i try to compile the code in NiosII but there is many error ,this code permit to compression image , i have 2 code of compression (h.264, and the library openjpeg)this two codes are runnable in visul studio c++,my problem is how to execute this codes in NiosII, plz i need your help. thanks in advance.

first of all you need a nios-ii, and in eclipse create a application like Hello Word, rename this hello word to your desire name , if you r code won't taking any OS related stuff's make sure you should add all the relevant header file in this project, and copy past you h.264 main file to your application.add related C file also. the best way is to go through the simple socket example. you need lot's of memory also so batter to use some high end FPGA which development board you are using...? what are the error's...?

thank you sir ,I use a Altera fpga stratixII ,i download a source code from h.264 from this link ,the error in nios II is ./block.c:27:20: memory.h: No such file or directory make: *** [obj/block.o] Error 1. also this code of h.264 support a file (.cfg) so can i converted from extension (.txt) ? because NiosII don't support this type of file(.cfg).thanks in advance.

Hello Sinam,
Please clarify what type of "traitement of image,", i have previous experience of image compression in C and FPGA.

hi Kaushal,
the traitement is extract a matrice of covariance from the image, the problem is the capacity of memoire (SDRAM,..) because the size of image is very big.So question is how to optimize the code source,Or to accelerate it.
