There are two arm instruction sets and thumb instruction sets.
The arm instruction set is 32-bit long and has the most complete functions. The thumb instruction set is 16-bit long and can implement most of the functions of the arm instruction set.
Thumb instruction set is extremely highCodeDensity (reduced by 30% on average ).

It's only a few days from 11 Golden Week, National day when there are one weeks holiday, for busy friends, the National Day of the week seven days long vacation really can count on the Golden Week, now work pressure is larger, take advantage of National day, to travel relax mood is really a good choice. Also some people are fans, National Day holiday can enjoy playing a few days of games, as long as their own computer configuration good enough, and holidays have time, it is certainly a happy, if
Difference between von norann Implementation Harvard Implementation of ARM
Von norann implementation: data items and instructions share the same bus.
Harvard implementations: It uses two different buses.
Load-store architecture:
Load: Memory ----- (load instructions copy data) -------> registers in Core
Store: registers ---- (store instructions copy data) ------> memory
There are no data processing instructions that directly manipulate data in memo

Users need to assemble a computer, the first need to build a set of suitable for their own computer configuration, if the configuration is not suitable for their own affirmation is not, for example, they like to play a large game, and configure the performance of the game is not strong, large games will play up to compare cards, so want to play
Computer configuration is not difficult to build, as long as the computer hardware with each other to ensure compatibility between the hardware, which i
With the growing number of mobile device platforms, and even the momentum to replace the desktop platform, the word "arm" is increasingly appearing in people's eyes, especially on mobile phones or tablet processors, but never see arm's processor, but "the adoption of ARM's latest architecture" processor. In fact, ARM (

The ARM microprocessor generally has two working states and can be switched between them:
The first type is the arm State. At this time, the processor executes the 32-bit arm command;
The second is the thumb S
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 PC

In this paper, the embedded multi-core processor adopts isomorphic structure to realize parallel execution of the same piece of code on different processors.

ARM announces the launch of the latest 32-bit cortex-m processor CORTEX-M7, which delivers up to twice times more computing and digital signal processing than the currently highest-performing ARM architecture microcontroller (MCU) ( DSP) performance. The ARM cortex-m7 processor
access process cannot be 0. Conversely, if va[31:25] equals 0, the address VA to be accessed is within the process's own address space, so a process context switch is made to convert VA to MVA, where the PID of the above formula is the PID number of the process.

Interrupt handling of ARM processors1) There are 8 operating modes in the arm processor (and the CPU handles different task modes), typically 5 Abnormal mode, In these 5 Modes There are three interrupt mechanisms, namely the FIQ mode (High priority interrupt mode);IRQ Mode (Low-priority interrupt mode), and one that is the SVC mode (the mode generated when the r
commands, variable instruction lengths, and multiple addressing methods. These are also the disadvantages of CISC, because they greatly increase the difficulty of decoding, however, with the current high-speed hardware development, the speed improvement caused by complex commands is far less than a waste of time on decoding. In addition to the x86 instruction sets used in the personal PC market, CISC is no longer needed for servers and larger systems. The reason why x86 still exists is to be co
