prediction unit based on saturation counter and BTB, and finally realize the prototype of the branch predictor by using Verilog. The realization has some advantages in the area, which can be applied to the experiment and verification of microprocessor, and the design also has some shortcomings:(1), in the case of the value of the hash of the PC value, only simple to take the PC low 10bit of data as BTB index, which will lead to high PC value of the same branch instruction record state is confus

Intel announces silvermont microarchitecture, a new design in Intel's 22nm tri-gate SOC process delivering significant increases in performance and energy efficiency. Silvermont microarchitecture delivers ~ 3x more peak performance or the same performance ~ 5x lower power over current-generation Intel Atom processor core.1 Silvermont to serve as the foundation for a breadth of 22nm products targeted at ta

Deep understanding of Intel Core microarchitecture Level 2 cache of Core 2 Level 1 cache is divided into 32kb l1i cache and 32kb l1d cache, which are both 8-way groups of associated write back buffer, 64 bytes per line. Each core has an independent L1 cache, shared L2 cache and bus interfaces. L2 cache is a 16-Channel group, with 64 bytes per line. The data bandwidth between L2 cache and L1 cache is 256bit. Two core l1d caches can transmit data to e

only be used within a function are called "local variables".Note: The var keyword is omitted anywhere, and the variables defined are "global variables" (which can be used outside of the function) so, in general, do not omit the var keyword.Assignment Value and assignment address:Assignment value: Used to assign a basic data type (only one value) to a variable.Reference address: Used to assign a composite data type (possibly with multiple values) to a variable. All two variables change at the sa

It took me a long time to finish reading Steven Webster's introduction to the cairngorm microframework. To sum up, there are three most impressive parts, 1. The globally unique ModelLocator and DataBinding simplifies the management of the client

To recap, in the previous introduction to Spring Cloud Config, we left a suspense: how to implement real-time updates to configuration information. Although, we have been able to implement the property update of the application triggering the

To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good or the macro definition good? This requires u

In the previous article, we tried to use list template to help us quickly create a schema in our list definition.

Python array definition method, python array Definition This article describes how to define Python arrays. We will share this with you for your reference. The details are as follows: Python does not have an array data structure, but the list is similar to an array, for example: a=[0,1,2] In this case, a [0] = 0, a [1] = 1, a [[2] = 2, but a problem occurs, that is, what if array a is to be defined as 0 to

Character array definition problem, character array Definition The problem code is as follows: # Include # Include # Include Void parse (char * buf, char * args []){Printf ("buf = % s \ n", buf );Int I = 0;While (* buf! = '\ 0 '){Args [I] = buf;While (* buf! = '') (* Buf! = '\ T') (* buf! = '\ N') buf ++;While (* buf = '') | (* buf = '\ t') | (* buf =' \ n ')){* Buf = '\ 0'; // pay attention to this rowB

　　They have a common advantage is "change the whole, to avoid the input error" What are the two different? Some.The main difference is that the macro definition is done prior to compilation, and the const is processed during the compilation phaseMacros define constants that do not occupy memory cells and are defined by const occupy memory unitsA macro definition has the same effect as a const constant-----t

JavaScript scope, context, definition and call of function objects, definition and call of anonymous functions, and closureThe introduction of closures always gives people a deep feeling that there are countless examples on the Internet. However, I found that a considerable amount of data is not easy to understand. According to my observations, these examples combine the concepts mentioned in the title and

int x = 1234; it is a variable declaration plus definition. Variables can be declared repeatedly, as long as they do not conflict with each other, but can be defined only once.However, const int x = 1234; is also the global definition of "variable" (if declared, it should be const int X;), but can appear in the header file, when multiple CPP files contain this header file, it is equivalent that each CPP fi
