Recently, Intel released three new Haswell core desktop processors, respectively, i7-4790, i5-4690 and i3-4360, using better thermal conductivity and packaging materials, so the frequency is higher, theoretical performance is stronger. At the same time, the 9 Series Chip Group also came out together, joined the SATA Express and m.2, such as fast storage technology support, the largest 16GB cache boot technology, the overall performance is more powerfu
If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core
. Describes VRAM.
VRAM (Video RAM) holds displayable video data. When CRT monitors are used, VRAM is dual ported, allowing one port to continuously refresh the display while another port writes data to the display.
VRAM saves the displayed video data. When a CRT display is used, VRAM is dual-port, allowing one port to refresh and the other port to write the data to be displayed.

Java uses the annotation processor to generate code-Part 2: annotation Processor
This article is part 2 of my "using annotation processors to generate code for Java" series. In the first part (please read here), we will introduce Java annotations and several common methods.
Now, in the second section, we will introduce annotation processors. This includes how to create annotation processors and how to r
I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday.
This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the ope
The annotations in Java are a magical thing that you don't know yet. You can see the custom annotations (Annotation) for the next hour. Now a lot of Android libraries are implemented using annotations, such as butterknife, we do not want to learn, we learn the note processor, we try to write a simple similar to the butterknife of things to bind the control.What is an annotation processor? The annotation
In the second lesson example, the first processor mapper and processor adapter are configured in Springmvc.xml, as shown below. configuration of the first processor mapper beannameurlhandlermapping - Beanclass= "Org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">Bean> Configure the first p
Extended image content processor: grayscale transformation and processor parameter problems
You want to extend the image processor to process the color of each independent pixel. You also want to change the processor parameters from the XNA main project.Solution
In the previous tutorial, you learned how to extend the c
Java thread exception processor, Java thread processor
Thread. UncaughtExceptionHandler is a static internal interface of the Thread class. This interface has only one method:
Void uncaughtException (Thread t, Throwable e), where t represents the Thread with an exception and the exception thrown by the e-table.
If an unhandled exception is thrown during thread execution, the corresponding unhandled exceptio

Mcu:micro Control Unit (microcontroller unit)
Mpu:micro Processor Unit (microprocessor unit)
The MCU integrates the on-chip peripheral devices, the MPU without peripheral devices (such as memory arrays), is a highly integrated general-purpose processor, and is the MCU that removes the integrated peripherals.2, MCU, MPU, DSP:

There are n tasks, each task has ri,di,wi, and the [Ri,di] representing the task represents the time interval in which the task can be done, while WI represents the workload of the task; now there is a processor, if it is executed at a speed of s, then the time required to complete the I task is wi/s; Required to calculate the minimum value of the maximum speed during processor executionThe idea is very

Introduction to DBUtils result set Processor and dbutils result Processor
Common-dbutils.jar is an open-source tool library provided by the Apache organization for simple encapsulation of JDBC, which can simplify the development of JDBC applications without affecting program performance.

C pre-processor, processor
The C Preprocessor is not a component of the compiler, but a separate step in the compilation process. The C Preprocessor is just a text replacement tool that instructs the compiler to complete the necessary preprocessing before the actual compilation.
All Preprocessor commands start with. It must be the first non-null character. To enhance readability, Preprocessor commands shoul
The official explanation is as follows. I haven't figured out why. I didn't execute two identical select into statements as described below. I still reported this error, and after I changed it using the first method, I only passed the test for the first time, and this problem occurs later. Then I changed it to the second method and tested it several times. So far, no error has been reported. In addition, I use JDBC to execute SQL statements. I place the first and second SQL statements (original
The above two articles introduce two typical and simple parallel methods, and briefly introduce their performance and advantages and disadvantages. Here we will introduce another method:Micro-ThreadTo synchronize multiple parallel tasks.
Let's imagine the problem below the limit: To search for an element in a known-length huge linear table (such as a one-dimensional array), and all the elements in the table are unique. The processor we use now has two

For wireless system design engineers, it is critical to have a clear understanding of the differences between multithreading (MT) on a single processor and using multi-processor (MP) processing. Cellular phones are the first large-scale application to implement dual-core design. However, dual-core implementation is also applicable to many wireless applications that require high performance and low power con
