My God, this article speaks about the instruction format and transmission of the processor: [63:61] [60] [59:54] [53:48] [47:42] [41:0] Conditioncode dataswitch OPCode targetreg secondreg Else Conditioncode is a conditional code, simplified after the remaining 6 (==,!=,>, Dataswitch, if you set 1, then the other part represents a 32-digit or 42-bit address, and if 0 it says only [41:36] represents the register. opcode for opcode, not explained, attach

"While there is a suspicion of advertising for Intel, the effects of Intel's deep-rooted, I-series processors over the years are sh

companies alone produce 4 billion arm processors a year, more than half the world's population. So, the world we live in is supported by processors that are several times more than the total population of the Earth. In addition, Google and other social backbone systems such as search, bank ATM, railway transportation system are inseparable from the processor, we can not imagine life without these systems. Looking back on history, people have spent a

register is 0, the microprocessor can switch from the thumb status to the arm status when the Bx command is executed. In addition, when the processor performs Exception Processing, it puts the PC pointer into the exception Mode Link register and starts to execute the program from the exception vector address, which can also switch the processor to the arm state.

At present, embedded multi-core processor has been widely used in the field of embedded devices, but embedded human system software development technology still stay in the traditional single-core mode, and do not give full play to the performance of multi-core processor. Program parallelization optimization At present in the PC platform has certain use, but in t

. The second advantage is that. xnb files are platform-independent and can be used on both PC and Xbox 360 platforms. Let's analyze the compilation process, because this process is executed every time the project is compiled. This process is divided into three sub-processes: Importer: reads source files and extracts useful data. The data is stored in a specified standard format. For example, for a model, the standard format is NodeContent object and

Recently, the hype over dual-core processors has been so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel are praising the merits of their dual-core processors through their websites. Such campaigns are timely, as most industry watchers believe the dual-core processors will be in the pipeline in 2006. But behind these phenomena, and in the many related media reports, there are hidden truths that are not known and unusual. Below, we'll tell you

executed. Registers can store data elements to be processed without having to access the internal memory cells. However, the number of registers built into the processor chip is limited. The IA-32 platform has multiple sets of registers of different lengths. The general register is used to temporarily store data, the segment register is used to refer to the memory location, the instruction pointer register, also known as the program Counter (

instructions, and then the assembler program is used to translate the programs into 0 and 1 encoding. It is essentially the same. 1-2. This is the simple usage model of the computer, whether it is video software, browsers, or any other software; whether it is developed using C # development, Java Development, or any other language; whether running in windows, Android, or any other platform, whether running on arm processing or Intel processor, or on

I will upload my new book "self-writing processor" (not published yet). Today is the eighth article. I try to write this article every Thursday. 2.7 Circuit Design Example In this section, we will design a simplified processor command acquisition circuit, through which we can use the example to understand the use of Tilde. There is usually a PC register inside t

certain protected system resources, cannot change mode unless an exception occurs Privileged mode: Free access to system resources and change mode in addition to user mode System mode: Exception entry is not allowed, same register as user mode, not restricted by user mode Processor Status The CORTEX-A8 processor has 3 operating states, which are controlled by the T-bit and J-bit of the CPSR register. L Ar

The history of 64-bit computing is quite rich and interesting. Companies such as Cray have started using 64-bit registers in their systems in the 70 's, but the truly pure 64-bit computations didn't really come until the 90 's. The first is the R4000 of MIPS, then the DEC Alpha processor. By the middle of the 90, both Intel and Sun had 64-bit designs. The real turning point for consumers is that AMD released a 64-bit

, thinner, faster and easier to use than the traditional PC card technology. In addition to the EXPRESSCARD34 for laptops, there is a ExpressCard54 for desktop computers, which bridges the laptop to the desktop. Because ExpressCard achieves a more ideal balance between the dimensions, performance, reliability, adaptability, hot-swappable, and automatic settings, it is likely to replace the PC card that has

Overview Smartphones both contain two processors. The "Dual Processor" mentioned here is not two microprocessor kernels, but two processor platforms-application processors and baseband processors. Essentially, a smart terminal includes multiple microprocessor kernels, in addition to the control kernel of the 4-core, 8-core, and baseband processor of the applicati

The book on arm often says that because of the pipelining feature, when the program counter is read during instruction execution, the read value needs to be the current instruction +4Never understood at first, today by a great God gave away the essence of ....The program counter (PC) always points to the "fetching finger" instructionSince arm is a Level 3 pipeline, when the nth instruction is being executed, the n+2 instruction is actually being evalu

In fact, the author later felt that this article is actually not
