Hello, My input data is 16-bit data, and I need to find a median of 3 values using SSE2 instruction set. If I have 3 16-bits input values A, B and C, I thought to do it like this: D = max( max( A, B ), C ) E = min( min( A, B ), C ) median = A + B + C - D - E C functions I am planing to use are : max - _mm_max_epi16 min - _mm_min_e...

Hi everybody, I've been working on an AES CUDA application and I have a kernel which performs ECB encryption on the GPU. In order to assure the logic of the algorithm is not modified when running in parallel I send a known input test vector provided by NIST and then from host code compare the output with the know test vector output prov...
printf conversion specifications are % followed by flags, width, precision, length modifier and conversion specifier. Is there practical limit to size of a conversion specification? I.e. %s is 2 chars long, while %08.2f is 6 chars long. My question is, what is the length of the maximal single specification in a format string that can be...
For regular expression \w+\d, in many script language such as perl/python it can be written literally. But in C/C++, I must write it as: const char *re_str = "\\w+\\d"; which is ugly to eye. Is there any method to avoid it? MACRO are also acceptable. ...
Possible Duplicate: In what order does evaluation of post-increment operator happen? Consider the following snippet(in C): uint8_t index = 10; uint8_t arr[20]; arr[index++] = index; When I compile this with gcc, it sets arr[10] to 10, which means that the postfix increment isn't being applied until after the entire assign...

Hi all, I have a simple memory mapped interface, and I would like to write through this values to two registers and then read them back. The following code example works fine: volatile int *reg1 = (int *) 0x80000000; volatile int *reg2 = (int *) 0x80000004; *reg1 = 12; *reg2 = 23; printf("reg1 = %i\n", *reg1); printf("reg...
I'm having a very tough time debugging a multi-threaded C application that I've made a few changes to. I've been unable to use GDB to help identify the issue(see below code for more info). The following code is from one of the tasks that is opened in its own thread. I've snipped out most of the code following the problem. void tskPr...
Hello newcomer here (be gentle), I am attempting to write a program which has floating point code in it. However this program needs to run on 2 different processors. Which have roughly identical ISAs except for their floating point model. They use completely different instructions and registers to do floating point calculations. Wha...

Guys, I have a value thats 5 bits in length. 4 bits determine the number and the 5th bit determines the sign, there by holding any value between -16 and +15. How can I accomplish sign extending from a constant bit width in C#? I know in C, I can use something like the follow to accomplish this: int x; // convert this from using 5 bits ...
