2.1 General Concepts
1. The central processor unit (CPU) contains registers and what other basic elements?
TheClockSynchronizes the internal operations of the CPU with other system components. The clock synchronizes internal CPU operations and other system components.
TheControl Unit(Cu) coordinates the sequencing of steps involved in executing machine instructions. The Control Unit coordinates the steps in the machine instructions.

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
DescriptionWhen LoadRunner is monitoring Windows system resources, running the Discovery report following error after adding good Windows resource:Int:Check that there was such a measurement on the This machine.Check that, selected the right platform. For the monitored machine in the Add Machine dialog box.Note:when you monitor a Win2000 machine from an NT, some counters is not being available.Try to delete this measurement and add it again (use the Add Resources dialog box) (Entry point:cfactor
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
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
1, MCU, MPU:
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:
Dsp:digital Signal
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

Development process1. Modify the Springmvc.xml file as follows:XML version= "1.0" encoding= "UTF-8"?>Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2
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
My God, this article speaks about the instruction format and transmission of the processor:

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.

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
, and delivers the request to the next processor. At a point, create a response and return it along the chain. This mode is calledDelegateProcessor (DelegatingHandler) (5-1 ).

1 socket, core, thread(1) Socket is the number of slots on the motherboard to plug the CPU, that is, the administrator said "road"The chip manufacturer encapsulates one or more cores on a chip, called a socket. Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on. Single-core (Single-core) and multicore (multi-core) are also known as uniprocessor and multiprocessor(3) th
core typically multiplies the processor's computational resources.
What conditions are required before hyper-Threading is implemented
processors, BIOS, operating systems, and workloads form the four basic elements that a hyper-threading server should have. Most contemporary operating systems can support hyper-threading: In 2002 Intel introduced the currently sophisticated hyper-threading technology into the Xeon
commands, you can use a smaller crystal area to produce faster processors. This idea was so successful that in 1984, the MIPs computer system company was established to commercialize the mips architecture. Over the next decade, the mips architecture has been developed in many aspects and has been applied in workstations and server systems. The mips architecture also evolved from MIPs I, MIPS II, MIPS III, MIPS IV, MIPS V, and mips32 to mips64. John H

The load mean can be seen in the uptime or the top command, and they may appear like this:Many people will understand the load mean: Three numbers represent the average system load (one minute, five minutes, and 15 mi
