I a开发者_StackOverflow中文版m learning C with \"The C Programming Language\", 2nd edition, and also doing each exercise.
I\'m trying to optimize an image format conversion on iOS using the NEON vector instruction set. I assumed this would map well to that because it processes a bunch of similar data.
I\'ve literally just started programming in assembly language this week and I\'m having some trouble.I\'m making a program in MIPS using PCSpim and the program prompts the user to enter two non-negati
I\'m writing a small assembly routine called isOdd, which, as the name implies, returns if the passed integer is odd, by returning 1 from a % operation.
I\'m working ona toy programming language. I use LLVM to generate machine code. Now my question is: How do you implement a printf() function from scratch?. In a C progra开发者_运维问答m you call into
Not finished with this problem In this program an unknown problem causes the assembler to reject the code because of apparently unknown macros, or what looks to the assembly like macros. I\'m not s
It is possible to re-express: i % m as: i & (m-1) where, i is an unsigned integer m is a power of 2 My question is: is the AND operation any faster? Don\'t modern CPUs support integer
While reverse engineering I came around a very odd program that uses a calling convention that passes one argument in eax ( very odd compiler ?? ). I want to call that function now and I don\'t know h
So this program was for an assignment. The due date passed and I turned in what I had and got a good grade, but this bug has been bothering me. It\'s not technically an a开发者_开发百科ssignment anymo
