UbuntuControlCenter (UCC) 0.6.1 released an update. This version is inspired by the layout of the manriva control center, a famous Linux release. It is not an official application, but is concise in design, allowing users to easily set up relevant systems. UCC allows you to easily set various system settings, such as low-quality and high-quality video cards. This version adds the system hardware information

Cisco Unified Communication, a company that proposes unified communication, is there any new action for Unified Communication in the era of cloud concept flooding? Now let's take a look at this consultation. So what is a new UCC solution made by BT, which is combined with Cisco's Unified Communication Technology? BT and Cisco today announced the use of the BT Onevoice UCC service portfolio to launch a cloud

reading the questions, I thought of the topological sorting. I connected the site that did not appear in the train departure station and the terminal station to the site that appeared with a directed edge, you can find several layers of Topology Sorting. However, there is a problem here, that is, the reading of O (Mn ^ 2) and a large amount of computing, so the reading is slightly reduced by some loop range, the read complexity of the worst O (Mn ^ 2/4) is reached. In the topological sorting, t

Semantic checking of 4.2.4 function callsIn this section, let's discuss the semantic check of function calls, syntactically, the corresponding expression of a function call belongs to the suffix expression postfixexpression,ucc compiler exprchk.c function Checkfunctioncall () A semantic check of function calls was completed, as shown in 4.2.18. When reading this code, you need to understand the syntax tree after parsing for the function call, please r

epilogue always have finalizing, Unconsciously we have completed the UCC compiler analysis, all the way, the deepest experience is still "paper on the end of light, it is known that the matter to preach." According to this principle, the best way to understand the UCC compiler is to "read directly its source code, thi

5.1 Intermediate code Generation and Optimization _ IntroductionDuring the parsing and semantic review phases, we are always dealing with the 3 concepts of statement statement, expression expressions, and externally declared externaldeclaration. Through the declaration, we finally established the corresponding type structure, and in the symbol table holds the correlation identifier type information, in the intermediate code generation phase, we no longer need to deal with the external declaratio

C compiler profiling-managing the register for generating assembly code In a computer, the CPU speed is much faster than the memory speed. The compiler should make full use of register resources to reduce unnecessary access to the memory, this increases the speed of the compilation code generated by the compiler. In the intermediate code generation stage, the UCC compiler uses the temporary variable t to store the values of common subexpressions such

In the computer, the CPU speed is much faster than the memory speed, the compiler should make the best use of register resources, reduce unnecessary access to memory, thereby increasing the compiler generated by the assembly code run speed. In the intermediate code generation phase, the UCC compiler holds a temporary variable T to hold the shape as "t:a+b;" The value of the common subexpression of the assembly code generation, the

6.1 Introduction to assembly code generationAfter lexical analysis, parsing, semantic checking, and intermediate code generation, we finally came to the "target code generation phase" because the UCC compiler's target code was the 32-bit x86 assembly code, so we called this chapter "assembly code Generation". Most of the source code in the UCC compiler is for Windows and Linux platforms, but the default ass

C compiler profiling _ 5.2.3 intermediate code generation and optimization _ access array elements and struct members through "offset" Section 5.2.3 accesses array elements and struct members through "offset" In the previous section, we introduced the access to "array elements and struct members". We use the "base address + offset" mode to calculate the address of the memory unit. For the array element arr2 [I] [2], the array index value I is a variable, and the corresponding address must be exp

6.3.1 The main process of generating assembly code from intermediate directivesIn this section, we can focus on "how to translate an intermediate code into assembly code". The intermediate code for the UCC compiler is a four-tuple, including operators and 3 operands, as shown below.Of course, some intermediate code only need to use opcode and DST, for example, the unconditional jump instruction "goto BB2;" There is no need for SRC1 and SRC2. To facili

Let's take a look at how the UCC compiler handles strings, as shown in 4.2.8.Figure 4.2.8 String StringLiteral Figure 4.2.8 the 1th to 11th row of HELLO.C has 5 strings, visible from line 15th to 20th, except for the "123456" that initializes the global array buf[], the UCC compiler names several other strings.

Unified Communication is not the same as unified Interaction UC is continuously warming up, but can it solve the problem of communication disconnection? The new system must take UC further to support real unified interaction. The use of unified communication and collaboration (UCC) or Unified Communication as a service (uCaaS) is expected to increase rapidly in the next few years, because these technologies can integrate multiple channels into a sin
