(operands ). For example, the arm system is R0 to R15, so four bits are required to represent it. Of course, the arm register also has the concept of a group, that is, the registers that the CPU may see in different working modes may be different, such as R13 and R14. During decoding, not only the instruction operand must be used as the input, but also the value of the Current Status Register must be used as the input. What is the reason for the 16-b

Several situations returned by arm exception interruptionsImportant basic knowledge: R15 (PC) always points to the instruction that is taking the finger, instead of the instruction that is executing or decoding. In general, it is customary to refer to the first instruction as a reference point, so PC always points to the third instruction. When the arm status is set, each command is 4 bytes long, so the PC always points to the command address plus an

Apple watches are currently 32-bit. This is most likely because 32-bit ARM CPUs typically have a smaller power than their 64-bit siblings. This is important for the watch because the battery is very small.X86_64 Register calling conventionYour CPU uses a set of registers to process the data that is running. These are storage devices, just like the memory in your computer. However, they are located on the CPU itself, very close to the CPU portion. So the CPU accesses them very quickly.Most direc

ARM Architecture and programmingThis article records some of the books that read "ARM architecture and programming".Personally, when learning arm system, do not need to memorize, as long as some key to the general memory, such as ARM Register (General Register, PC, LR, SP, CPSR, SPSR), ARM interrupt processing system, commonly used arm assembly instructions.This article is basically from the book, are some of the key knowledge, need we often go to review.I.

, vector analysis and the realization of virtual reality provide the hardware Foundation. By providing more registers, CPUs produced in accordance with the X86-64 standard are more efficient at processing data and can transmit more information in a single clock cycle. EM64T Technology Intel officially defines it for EM64T: the EM64T full name Extended Memory Technology, which extends 64bit memory technology. EM64T is an extension of the Intel IA-32 Architecture, IA-32E (Intel Architectur-32 e

The ARM processor uses an assembly line to increase the speed of the processor's instruction flow, allowing several operations to be performed simultaneously, and making the operations between the processing and memory systems smoother and more continuous, providing 0.9mips/mhz instruction execution speed. The PC represents the program counter, the pipeline uses three stages, so the instruction is divided into three stages: 1. Refer to (Load an instruction from memory); 2. Decoding (identifying

LR. The register is used to hold the return address of the subroutine. Register R15 is called a program counter and is recorded as a PC. 2 The use rule of the stack atpcs the stack with the full decrement type (fd,full descending), that is, the stack grows downward by reducing the memory address, and the stack pointer points to the lowest address that contains the valid data item. 3 The first 4 of the parameter's pass rule integer parameters are pass
