I\'ve got a case where I need to compress a lot of often small values. Thus I compress them with a variable-length byte encoding (ULEB128, to be specific):
UPDATED - Check Below Will keep this as short as possible. Happy to add any more details if required. I have some sse code for normalising a vector. I\'m using QueryPerformanceCounter() (wrapped in
I\'m working on a granular dynamics problem. The computationally expensive part is the function below that solve a quadratic equation to detect the collision of two particles.
SSE and/or 3D now! have vector instructions, but what do th开发者_C百科ey optimize in practice ? Are 8 bits characters treated 4 by 4 instead of 1 by 1 for example ? Are there optimisation for some ar
I\'d like to compare performance of an application across multiple SSE versions and have been unable to find the values that are accepted by this JVM flag. I\'m testing 0, 1, 3, and 4. I\'m most unsur
Why does _mm_extract_ps return an int instead of a float? What\'s the proper way to read a single float from an XMM register in C?开发者_StackOverflow
I have an application created using VC++, and wanted to explore optimization opprtunity开发者_运维技巧 by vectorizing some operations.
I have two questions about X86 processors. First: What is SSE? What is it for? Is it CISC architecture?
I am currently getting started with SSE. The answer to my previous question regarding SSE ( Mutiplying vector by constant using SSE ) brought me to the idea to test the difference between using intrin
I have some code that operates on 4D vectors and I\'m currently trying to convert it to use SSE. I\'m using both clang and gcc on 64b linux.
