ASSEMBLY LANGUAGE
An assembly language is a low-level programming language for a computer, microcontroller, or other programmable device, in which each statement corresponds to a single machine code instruction. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple systems.
Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code.
Assembly language uses a mnemonic to represent each low-level machine operation or opcode. Some opcodes require one or more operands as part of the instruction, and most

The popular arcade game NBA Jam (1993) is another example. Assembly language has long been the primary development language for many popular home computers of the 1980s and 1990s (such as the Sinclair ZX Spectrum, Commodore 64, Commodore Amiga, and Atari ST). This was in large part because BASIC dialects on these systems offered insufficient execution speed, as well as insufficient facilities to take full advantage of the available hardware on these systems. Some systems, most notably the Amiga, even have IDEs with highly advanced debugging and macro facilities, such as the freeware ASM-One assembler, comparable to that of Microsoft Visual Studio facilities (ASM-One predates Microsoft Visual Studio).
The Assembler for the VIC-20 was written by Don French and published by French Silk. At 1,639 bytes in length, its author believes it is the smallest symbolic assembler ever written. The assembler supported the usual symbolic addressing and the definition of character strings or hex strings. It also allowed address expressions which could be combined with addition, subtraction, multiplication, division, logical AND, logical OR, and exponentiation operators.
COMPILER
A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language, often having a binary form known as object code). The most common reason for wanting
First let us take a look at computer programming. This element takes on different program designs created by engineers and uses one of several different programming languages to write executable code that computers can read. Programming is the source for
4) The two mechanisms which used to translate a program written in a high-level language into a machine language are:
The objective of this lab is to be able to understand how the CPU functions work, as well as understanding machine and assembly language.
Haswell introduced new instructions for x86 ISA, divided into four categories. The first one is AVX2 which uses integer SIMD instructions from 128-bits to 256-bits whereas the original version was a 256 –bit extension using YMM registers, mostly the floating point instructions. In addition Haswell also had Intel’s Fused Multiply Add (FMA) which includes 36 FP instructions that performs 256-bit computations and 60 instructions for 128-bit vectors.
The Massachusetts Bay Transportation Authority adds a new station to the orange line for easy commute to new development project, Assembly Row. Also, an increase in fares is installed as a result of newly added later running services, which run until 2:30 am on weekends.
The lw instruction is Load Word which loads whatever is stored in the memory at address location 300+content of $t2 and stores it in register $s3.
Machine code it the language that the computer understands. High level languages are better because they are easier to understand and work with.
Algorithms are set of steps for solving a problem; algorithms also make the program faster. For example, when you are checkers games and you want the user to be able to play against the computer. Computer scientist must figure how to a checkers’ program that never loses by using the minimax search algorithm to search through the huge tree of possible moves. Another interesting topic that I learned in the video is object code. Object code is the output of a compiler after processes source code; source code was written by a human in a programming language for a computer program. A compiler is a conversion of source code into object code. Object code is usually a CPU, but sometimes it designed to convert source code into an assembly language or into some other programming
A: The machine code is the language which the computer hardware understands and executes. It is preferable to write programs in a high level language such as C ++ because it is much easier to understand and learn this machine language.
address calculation of instructions - this determine the address of the next instruction to be processed.
The primary defining characteristic of IA-32 is the availability of 32-bit general-purpose processor registers (for example, EAX and EBX), 32-bit integer arithmetic and logical operations, 32-bit offsets within a segment in protected mode, and the translation of segmented addresses to 32-bit linear addresses. The designers took the opportunity to make other improvements as well. Some of the most significant changes are described
Each programming language uses a piece of software, called a compiler or an interpreter, to translate your program code into machine language. Machine language is also called binary language, and is represented as a series of 0s and 1s. The compiler or interpreter that translates your code tells you if any programming language component has been used incorrectly. Syntax errors are relatively easy to locate and correct because the compiler or interpreter you use highlights every syntax error. If you write a computer program using a language such as C++ but spell one of its words incorrectly or reverse the proper order of two words, the software lets you know that it found a mistake by displaying an error message as soon as you try to translate the program.
Object-oriented programming (OOP) and procedural programming are two programming paradigms. Procedural programming is a method of writing software. It is a programming practice centered on the procedures or actions that take place in a program. Object-oriented programming centers on the object. Object-oriented programming creates objects from abstract data types that encapsulate data and functions together (Gaddis 2010). There are many similarities
structures atom by atom ("Engines" 12). Along with the assemblers comes its opposite, the disassembler.
Now computers can’t just use English they have to tell the computer in one of its many different languages that can be changed into binary code, what you want it to do. “These languages range from high level and obscure to low level and popular” (“Defining High, Mid, and Low Level Languages”). Number wise there are very many, if you are just counting main languages there are at a minimum hundreds and if counting all of them including the obscure languages then over a thousand. Some of the more common ones some of you might have heard of them, mentioned previously Java which most every internet user has heard. Then there is C which “Programming in C is efficient and gives the programmer a great deal of control” (“How C Programming Works”). Java is actually built off of the language C. This language isn’t used very often but it has very many plus sides of learning it, this language can be used on different platforms; laptops, desktops, and smart phone. This language will also help with the understanding with many higher level languages. The last of the more common ones I am going to list is C++, which sounds an awful like C but it has a lot of improvements that C doesn’t necessarily have. It maintains the same simplicity as C but it also has features that make it easier to write for higher leveled programs. It can also make small
