Maintenance of assembly language is notoriously difficult, especially if another programmer is brought in to carry out modifications after the code has been written. Writing hundreds of lines of code consisting of ones and zeroes is an exacting and tedious process that accounts for the popularity of higher-level languages such as C and Java.
With the cortex-m series from ARM we are just now starting to be able to have C compete with asm, not that folks havent been using C or other higher level languages in their embedded products, but they have done it at a cost. So if by hardware programming you mean talking with your own CPU, then yes, assembler allows a bit more than C.
Machine language is the commands the processor directly knows how to carry out. This is a relatively straightforward process, there being a clear 1-to-1 transformation between assembly and machine language.
This is as opposed to compilers, which do a complicated transformation between high-level language and assembly.
It also was somewhat easier to use descendant, assembly language. It is directly executable and consists of what look to most human beings like a bunch of hexadecimal numbers, though a few geeks such as myself can tell it is code instead of numbers. Yes the syntax is easier, certainly.
The steering wheel, accelerator, brake, clutch and turn signal stalk are all in standard places, have standard behavior and the other controls are all clearly marked with ISO-standard symbols. Use a new processor and you need to learn a new language each time.
But when it comes down to the basics? C is far easier to maintain than assembler. What are the advantages of machine language? Easily Relocatable — Suppose that an assembly language program starts at address and we suddenly find that we have another program to be used with this program and also starts at location I believe it is a matter of personal preference.
Machine language is the native language of the machine, also knownas machine code. All the peculiar rules and syntax regarding type specifiers? This is not correct. For example, the instructions executing interrupt 21, service 10, are: This simplifies the programming process, as the programmer does not need to know or remember the exact storage location of instructions or data.
Unlike a high level language, assembler is very close to the machine language. Learning C is somehow more productive than learning assembler cause there is more developing stuff around C than Assembler. This is mainly because they are easier to understand and hence it is easier to locate, correct, and modify instructions, when desired.
Using machine code allows the programmer to control precisely what the processor does. Assembly is a low-level language. Advantage of machine language? Rather than binarycode, assembly language uses short mnemonics to represent eachmachine instruction, with symbolic representations for the CPUregisters.
After the source program has been converted into machine language by an assembler, it is referred to as an object program. When a component such as a video card or drive controller is changed, for example, the machine language code must be updated to recognize and address the new device.
C allows you to do all of that too, although you might have to rely on compiler-specific C code such as the interrupt keyword. Assembly is the same way; the complexity comes in what you add to it. Share on Facebook The purpose of any programming language is to transform a computer from an expensive electronic paperweight into a useful data processing and storage device.
The second instruction tells the assembler that the data of the program should stat at memory location Machine language is the actual bits used to control the processor in the computer, usually viewed as a sequence of hexadecimal numbers typically bytes.
Assembly language is a more human readable view of machine language.An assembler is a utility program which converts assembly language programs into executable machine codes, which is also termed as program billsimas.com would prov3e beneficial for you to procure Programming in Assembly Language Assignment Help from the experts to know more about it/5(K).
Advantages: Anything the processor is capable of can be programmed in assembly language, and assembly language is frequently the only way in which the hardware can be programmed. Disadvantages: Assembly language source code looks much messier than its high level language equivalent, it takes longer to write, and can be harder to read.
It is easy to program using c language rather than using assembly. C language can be quite faster than assembly language. It is possible to write assembly in C code but not C in assembly code. As a general rule, assembly language has no advantages over modern high-level languages with their modern optimizing compilers.
You can’t write tighter code in assembly language anymore. Today’s modern optimizing compilers are so good that converting high-level language to assembly language will NOT generally result in any improvement in.
Machine language addresses the computer's hardware directly, giving the programmer complete control over every aspect of a program's execution. The disadvantage to this approach is that the programmer must know the architecture of each chipset before he can write effective code.
After the code has been written by the user in a high level language it is then compiled into machine code by a program called Compiler or Assembler in the case of Assembly Language. – Explain why other languages were developed to allow humans to program computers.Download
