, c = 1. For non-addition/subtraction commands that combine the shift operation, C is the value that is removed from the maximum bit. Other commands C are usually unchanged. V: When an addition or subtraction operation is performed and a signed overflow occurs, V = 1; otherwise, V = 0. Other commands do not change. 2. Control bit. They will control whether the CPU responds to interruptions. I: indicates the position where the IRQ is interrupted. F: indicates the fast interruption prohibition bit

(1) Introduction to cross-Compiler A compilation program running in a computer environment can compile the code running in another environment. This compilation process is called cross-compilation. to put it simply, it is to generate executable code on another platform.(2) architecture and Operating System (1) common architectures include arm and x86 architectures. (2) common operating systems include Linux and Windows. (3) the same architecture can r

Overview build a kernel that is typically configured first and then compiled. This is the example of building the NEXUS5 kernel, codenamed Hammerhead. Configuration The usual approach is based on the vendor-provisioned configuration, which is configured to suit your needs. Command: Make Arch=arm Hammerhead_defconfig After execution, the "arch/arm/configs/hammerhead_de

Create an arm cross-compiling environment in ubuntu10.04 In Linux, the overall process of creating the entire arm cross-compiling environment is as follows: 1. Download the source file 2. Create a compiling directory in Linux and set Environment Variables 3. Create a kernel header file 4. binutils) 5. Create an initial Compiler (bootstrap GCC) 6. Create a glibc Library 7. Create a full set of compilers (fu

Believe it or not, just grab a man and ask him if he knows the CPU, I think his answer will be sure, but if you ask him again do you know the structure of arm and X86? What is the difference between the two? The vast majority of people must be a face. Today's small make up to take you in-depth understanding of the CPU of these two major architectures: arm and X86.
