";s:4:"text";s:4126:"Low level language abbreviated as LLL, are languages close to the machine level instruction set. In computer, there is assembler that helps in converting the assembly code into machine code executable. It is used for developing operating systems, device drivers, compilers and other programs that requires direct hardware access.1.Programs developed using low level languages are fast and memory efficient.2.Programmers can utilize processor and memory in better way using a low level language.3.There is no need of any compiler or interpreters to translate the source to machine code. As in, what language was the actual microcontroller programming done in?

Since, instructions written in low level languages are machine dependent. For both asm and C you would want to use open source tools (or your own in house tools) where you stand a better chance, even if it means using a virtual machine to run a 10 year old linux distro, of having tools available for the life of the product.The bottom line, again, use/learn/teach both C and asm, start with C and use asm where you can justify it. ADD for addition, SUB for subtraction, START, LABEL etc.

They are architecture dependent and there is a list of separate mnemonics for different computer architectures.Mnemonics gave relief to the programmers from remembering binary sequence for specific instructions.

(d) High level languages are user friendly than low level languages. The speed and small memory footprint advantages of machine language increasingly are outweighed by the difficulty of writing chip-level instructions in binary code.

Whether a language is high level or low level depends on the amount of abstraction it involves. 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. Low level languages – advantages and disadvantages.

Assembly language is coded differently for every type of processor. An assembler may translate the source code written in low level language to machine code.Low level languages are further classified in two more categories – Machine language and assembly language.Machine language is closest language to the hardware.

For assembly there's an unavoidable compromise between code maintainability and performance. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under Each and every programs were written as a sequence of binaries.A Programmer must have additional knowledge about the architecture of the particular machine, before programming in machine language. And so on. A low-level programming language interacts directly with the registers and memory. So if by hardware programming you mean talking with your own CPU, then yes, assembler allows a bit more than C. If you mean accessing external hardware, then assembler holds no benefit over C. But perhaps disadvantages, as it is often harder to write generic assembler code for a particular external device, than generic C code.Is a lot more flexible alluding you to work with memory,interrupts,micro-registers,etc.This is not correct.

I'm curious though, in what language was the .NET runtime, Java VM and Linux written in, for those microcontrollers? They provide less or no abstraction from the hardware. Detailed answers to any questions you might have They provide less or no abstraction from the hardware. Ultimately, programs written in a high-level language must be translated into machine language by a compiler or interpreter.

All the peculiar rules and syntax regarding type specifiers? It would be more fair to compare the performance of manual assembler versus a commercial compiler for that platform.gcc is multi-target so it does a pretty good job on average but not a great job for any particular target.
That code is mostly specific to that vendor or that specific chip so being in C has zero portability benefits, you have to rewrite fore each target anyway. Which PIC?
