Test Prep for Microprocessors—GATE, PSUS AND ES Examination

Unlike high-level languages such as Java and C++, assemblylanguage is much closer to the machine code that actually runscomputers; it's used to create programs or modules that are veryfast and efficient, as well as in hacking exploits and reverseengineering Covering assembly language in the Pentium microprocessorenvironment, this code-intensive guide shows programmers how tocreate stand-alone assembly language programs as well as how toincorporate assembly language libraries or routines into existinghigh-level applications Demonstrates how to manipulate data, incorporate advancedfunctions and libraries, and maximize application performance Examples use C as a high-level language, Linux as thedevelopment environment, and GNU tools for assembling, compiling,linking, and debugging

Gain the fundamentals of x86 64-bit assembly language programming and focus on the updated aspects of the x86 instruction set that are most relevant to application software development.

It’s also ideal for software developers who already have a basic understanding of x86 32-bit or 64-bit assembly language programming and are interested in learning how to exploit the SIMD capabilities of AVX, AVX2 and AVX-512.

Describing how the Assembly language can be used to develop highly effective C++ applications, this guide covers the development of 32-bit applications for Windows. Areas of focus include optimizing high-level logical structures, creating effective mathematical algorithms, and working with strings and arrays. Code optimization is considered for the Intel platform, taking into account features of the latest models of Intel Pentium processors and how using Assembly code in C++ applications can improve application processing. The use of an assembler to optimize C++ applications is examined in two ways, by developing and compiling Assembly modules that can be linked with the main program written in C++ and using the built-in assembler. Microsoft Visual C++ .Net 2003 is explored as a programming tool, and both the MASM 6.14 and IA-32 assembler compilers, which are used to compile source modules, are
