the page. When you place the mouse over the option, a prompt will appear to tell you what it is. The following describes these options in detail. --- Select implemention to optimize area (with lower instruction throughput): enables area optimization. If this is selected, implementation will optimize the area, especially reduce the number of pipelines, from 5 to 3. (Recommended: We recommend that you enable this option in a resource-tight architecture such as Artix-7. However, if you have perfor

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 application processor, DSP, and power management of th

Hardware and software are two parts of a chip system that are mutually dependent. This article summarizes the hardware and software components of a chip.(1) Hardware Master CPU: computing and control core. The basic architecture of the Baseband Chip adopts the structure of microprocessor + Digital Signal Processor (DSP). The microprocessor is the control center of the entire chip and runs a real-time embedd

Because our previous graduates are calculatedTherefore, our hospital has less contact with these enterprises. Our hospital is actively working hard and has established contact with its central branch office to seek internships or employment in these enterprises. (3) There are a few companies that often require masters or above to engage in embedded systems, mainly based on the diffi

---- Any microprocessor must be connected to a certain number of components and peripheral devices. However, if each component and peripheral device are connected directly with a set of lines, the connection will be complicated and even difficult to implement. In order to simplify the design of hardware circuits and system structure, a group of lines are commonly used and configured to connect with components and peripheral devices with an appropriate

"NetEase Science and Technology News" June 5, according to the Forbes website reported that Huang Renxun in 1993 to create Nvidia company, and successfully built the company into a graphics chip in the field of middle-aged revenue of 3 billion U.S. dollars of giant aircraft carrier. But Huang Renxun is not satisfied with making its chips a mere appendage of a traditional microprocessor. In this increasingly video-dominated world, he argues, graphic pr

software colleges in the formal colleges and universities have relatively few links with these enterprises. The formal University Software Institute is actively working hard, has already established the contact with some of them, strives for in the future to have the formal university software school schoolmate to these enterprise internship or the employment.(3) A small number of companies often want to master more than the embedded, mainly based on the difficulty of embedded. But most compani

, which leads to a problem: for the same data 100, it is possible that thread 1 executes x=100 while garbage collection performs the recovery of 100 operations, there is no clever way to solve this problem is to lock processing, such as, Code that guarantees that the Python interpreter can execute only one task at a timeGil protects the data at the interpreter level and protects the user's own data by locking themWith Gil's presence, same time in the same town. Only one thread is executedFor com

the interrupt condition is met, the CPU responds to the interrupt and goes to interrupt program processing. Turn off the interrupt signal receiver, save the scene (context), give the interrupt entry, transfer to the corresponding interrupt service program, process complete, return and resume the scene (context), turn on the interrupt signal receiverü Interrupt queuing and Interrupt award optimizationThe interrupt request is random, sometimes multiple interrupt sources are present and an interru

prevents multiple native threads from executing Python by Tecodes at once. This lock is necessary mainly because CPython ' s memory management are not thread-safe. (However, since the GIL exists, other features has grown to depend on the guarantees that it enforces.)Okay, does it look bad? A mutex that prevents multi-threaded concurrent execution of machine code, at first glance, is a bug-like global lock! Don't worry, we are analyzing slowly below. Why would there be Gil?Due to physical constr

thread wants to execute, must first get the Gil, we could think of Gil as a "pass", and in a Python process, the Gil has only one. A thread that does not have a pass will not be allowed to enter CPU execution. in python2.x, the Gil's release logic is that the current thread meets the IO operation or the ticks count reaches a maximum of (ticks can be seen as a counter of Python itself, specifically for the Gil, which is zeroed after each release, this count can be Sys.setcheckinterval to adjus

for multicore systems and absorbs some of the important features of other dynamic languages, such as not having to manage memory, such as null pointers and so on. Purpose of Creation The purpose of this new language is to solve a stubborn problem: software evolves much less rapidly than hardware, and software cannot really take advantage of the performance gains of multicore computing at the language
