full use of the values of relevant variables stored in each hardware register of the machine, to reduce the memory access times. In addition, how to make some adjustments to commands based on the features of machine hardware execution commands (such as pipelines, Proteus, CISC, and VLIW) to make the target code relatively short and the execution efficiency relatively high, it is also an important research topic.The compiled code after optimization mu

computer based on a simplified command system is called a simplified Command System Computer (RISC ). The central idea of the balanced architecture is that the command system should be simplified, and the Register operation commands should be used as much as possible. Besides the memory access commands (load and store), the operations of other commands should be completed within a single cycle, command formats are consistent, addressing methods are minimized, compilation efficiency is improved,

KVM, which means that the memory needs to be calculated only in kb when the program is running. KVM only needs 40 kb ~ 80 KB memory. At the same time, it is highly portable and suitable for 16-bit or 32-bit Proteus/CISC platforms. In the configuration layer, j2-defined two types of configuration: CDC (connected device configuration, connection-oriented device configuration) and cldc (connected limited device configuration, connection-oriented limited

processor is Samsung's arm core ). The chip is a cost-effective, high-performance 16/32-bit Proteus microcontroller based on Ethernet systems. The communication part adopts the BNC interface mode, and the signal output is coupled with the isolating transformer. The RJ45 connector is connected to the hub. In addition, the LCD display and keyboard input Local interface functions are designed. Timeout and retransmission mechanisms are used in multiple T

The Most Important Algorithms Http://www.risc.jku.at/people/ckoutsch/stuff/e_algorithms.html After a long discussion with some of my Proteus colleagues about what the 5 most important algorithms on the world are, we couldn't reach a consensus on this question. so I suggested to perform a little survey. the criterion for suggestions was that these algorithms shocould be widely used. further we restrict ourselves to the fields of computer science and

computers are much faster and more powerful than ARM-based systems in terms of performance. X86 CPUs can be larger than 1 GB, dual-core, and quad-core CPUs. Generally, 45nm (or even more advanced) processes are used for production. For arm, CPUs are usually several hundred megabytes, recently, about 1 GB of CPU is available. Generally, the process is less than nm. It can be said that in terms of performance and production process, arm is not the opponent of the x86 structure system. However, ar

I made a benchmark app running on iOS devices. We have tested the optimized and unoptimized PNG images and images of different sizes. The minimum time unit is 1 ms, which is not very accurate, but has enough reference value. Tests include 128x96,256x192,512x384,102 4x768 and 2048x1536. These include representative resolutions, optimized PNG, and unoptimized PNG, the compression quality ranges from 10 to 100% JPEG. Benchmark runs on iPad 1 + 2, iPhone 3G, iPhone 3G, and iPhone 4.

computer. Another optimization [You Hua] is mainly used to generate the target [mu Biao] Code [Dai Ma.For the previous optimization [You Hua], the main task is to delete the [Shan Chu] public expression [Biao Da shi], cycle [Xun Huan] to optimize [You Hua] (code [Dai Ma] out-of-context, and weaken the intensity of [Qiang du Xue RuO], changing [Bian Huan] loops [Xun Huan] to control [Kong Zhi] condition [Tiao Jian], merging of known quantities, etc), duplication propagation, and useless value as

determined by the user when the proxy is generated. In short, this improvement provides a low-cost and feasible solution for real-time monitoring at the cost of limited target system resources. 　　 Debugging does not only mean that the process of breakpoint-program pause-observation-continues, but also requires profiling, trace, and other means, however, the technological advances in modern microprocessor have brought difficulties to the implementation of these debugging methods.

The I2C bus transmits information between the bus and the device using two wires (SDA and SCL), serial communication between the microcontroller and external devices, or bidirectional data transmission between the master device and the slave device. The two communication lines are pulled up to + 5 V through the pull-up resistor. Each Integrated Circuit in the control sys
