I am working on a small bootloader for learning purposes. Is there any specification/information available about the (free) stack size required f开发者_JS百科or a bios interrupt call?before entering t
I just fini开发者_如何学Cshed up my Microprocessors class in college just a few weeks ago, there we programmed in assembly only. We learned a fair amount (IMHO) about interrupts.
A teammate made the following claim: \"Thread.interrupt() is inherently broken, and should (almost) never be used\".
Is it safe to use exte开发者_JAVA技巧rn data qualifier for a variable in an ISR?Assuming C: yes, but you need to mark the variable wth keyword volatile to let the compiler know its value can change in
Can someone explain what the following assembly code does? int 开发者_开发问答0x80 int means interrupt, and the number 0x80 is the interrupt number.
It\'s been a while since I did any ASM, and decided to once again try and write a small bootloader, testing with qemu. My issue is with interupt 13, for some reason the carry flag is being set, so the
Do CPUs (specifically powerpc) allow an interrupt handler to be installed for IPIs (inter processor interrupts) ? The MPIC I am using supports 4 IPIs per core and it has registers for setting the vect
I\'m writing a program in assembly using MIPS architecture for a class, and I\'m having trouble figuring out how to grab an input character by a user and store it in a register to process.
So this is a very particular question: I use开发者_运维技巧 an embedded system with a single CPU core.
Is it possible to disable all interrupts with a ASM/C/C++ program to get full control about the processor?
