Well, a group of Portuguese university researchers did and set out to quantify it. may have escaped your attention, as it did ours. Abstract: This paper presents a study of the runtime, memory usage and energy consumption of twenty seven well-known soft- c programming coursework help languages. We monitor the performance of such lan- guages using ten different programming problems, c programming coursework help, expressed in each of the languages.
We show how to use our results to provide software engineers support to decide which language to use when energy efficiency is a concern. Most people would take for granted that a computer program which runs faster will consume less energy. But this might not always be true, as other factors enter into the power consumption equation besides speed.
The team used a collection of ten standard algorithms from the Computer Language Benchmarks Game project formerly known as The Great Computer Language Shootout as the basis for their evaluations. Last year they updated the functional language results, and all the setups, benchmarks, and collected data can be found here.
Check out the paper for more details. Have your choice of programming language ever been influenced by energy consumption? Go Forth, be Conquered. It would be interesting to see where some of the esoteric languages fair on this sort of ranking. But I am very surprised that Rust came so close to C. Equally surprised that Rust beat Go by as much as it did.
The relationship between C, Rust, and Go is exactly what I expected to see and falls c programming coursework help in line with each of their design philosophies, c programming coursework help.
Rust is a low level systems programming language with no runtime and small standard library and lots c programming coursework help zero-cost abstractions making it feel high level. Rust was c programming coursework help few percent behind C 4 years ago; at the latest version of the benchmarking game, Rust is beating C gcc in 7 out of 10 benchmarks and beating C clang in 6 out of 10 benchmarks looking at time only.
Source required. From what I found so far Lua seems to be a fast language… among interpreted ones. If you looks closely most of the least performing language are interpreted. No magic happening there. You are confusing the LuaJIT and normal Lua. Actually LuaJIT is increasingly becoming the general Lua usecase, c programming coursework help.
A lot of software that embeds Lua is using LuaJIT as the default, c programming coursework help, and adoption of new versions of mainline Lua is pretty low. The question is what people usually do with LUA.
If you instead try to make it sort arrays within the language constructs itself, things change a lot. I have similar surprise with PERL, c programming coursework help, which I used a lot at a time to automate some functions where I needed max reactivity find a document containing a keyword, add it a comment, etc.
The main goals were a very small memory footprint for the runtime and for scripts. Absolute speed efficiency will not be of the same order as languages such as C. LuaJit is very close to the same speed as C.
Why anyone would use Lua without LuaJit is anyones guess, c programming coursework help. We have LUA but no BASIC or batch. I wonder how human written asm would fair, performing the same computations as the test, probably worse, for the average programmer. Also, I wonder what is gauge was used to tally c programming coursework help results, probably C, their favorite language. As others have stated, c programming coursework help, LuaJIT is very fast, I get about x performance improvement between LuaJIT and Lua in our game code.
the c programming coursework help tests look like they are run with the standard Lua interpreter. I graduated a software c programming coursework help bachelor in where we started with learning C, then were recommended to use C for most assignments after that, but we briefly touched upon most popular languages and what their pros and cons were in regard to computational efficiency, maintainability and initial development costs.
Wow, that is terrible. A proprietary Microsoft only language? It was a bit longer ago, though. And a couple Crays and an Intel Paragon for the fun stuff. Mac, NEXT, Coherent, etc. all worked fine for the majority of coursework anything where gcc ran was going to work great.
C and. NET is not propietary any more. Ah trigger word, and corrections in one day. And there are so many languages now!
Probably more languages than architectures. Back in my day, my university teach concepts of programming and not popular languages. They sometime purposely use obscured languages for the heck of it. We learn the programming part in tutorials and in the course of doing assignments. It c programming coursework help relatively to pick up similar languages. There are some odd languages e. Prolog, Lisp, APL. Community Colleges on the other hand teach programming for the hottest languages targeting the job market.
Came c programming coursework help to say the same. We learned Ada ~one of the reasons being that no-one would have used it before, so there would be no learned bad habits. The downside of using obscure abstract languages is that most people, over half of the students, learn things mostly by rote memory so the education is lost on them. If you teach them C, they can then program an Arduino. If you teach them Python, they can kinda-sorta program a Raspberry Pi. Computer Science still teaches Prolog, lisp, and whatever pet languages the professor has authored.
Software Engineering mostly teaches concrete languages in common usage. You learn how to design software programs in the real world in a team. And so on and so forth. Computer Engineering teach C, VHDL and assembly, IT learns stuff used in system administration, Web Development learns web languages. with any modern CPU, the compiler will beat the crap out of you optimization wise in It does not have to make readable code and can use tricks you would likely never try. Modern CPUs with pipelines, out-of-order executions, multiple cores and other bells and whistles are hard to optimize manually.
On the other hand, modern compilers have a lot optimizations for modern CPUs. Depends on the hardware surely. The classic Microchip PIC16c84 required its own C dialect, because it was very hard to use standard C with it, while the Atmega was designed to be programmed in C from the ground up, and there is little advantage to be gained in programming it in assembler, but you need to test to verify that!
There is plenty where the Atmega family still does better in ASM. Atmega is quite an old processor, so doesnt really have the hardware to drive neopixels neatly, at least if you want to do anything else. For driving neopixels, I would suggest moving to another processor family such as STM32, where you can drive multiple neopixel streams with very low overhead using a timer and DMA straight from C.
No asm required and you will have most of your processing power still available for other tasks. Offtopic, but I would guess RP also would do a nice job using its programmable PIO and 2 cores! Looking at the assembly language it output, there were lots of clear optimizations that it missed.
Overall I found that if I am having issues with GCC or need to start writing lots of assembler then it is probably time to move to a new processor. If that is Hi-Tech CI believe we tried it, but found that code was considerably larger and slower than our existing code with MPASM assembler. Not a fault of the compiler, c programming coursework help, but of the PIC architecture. As soon as c programming coursework help CPU becomes pipelined and gets an instruction cache, it becomes quite hard to handwrite efficient assembly.
The CPU tended to empty out those 4 bytes faster than new data could be put into it from RAM. C is often called machine independent assembly because, as Linus pointed out, by looking at c programming coursework help code, you can get a pretty good idea what the hardware is doing.
After a decade of coding in assembly, I was more than happy to switch to c for microcontrollers. I used assembler on every system I had from the mid70ers to the 68k days which was before x86 in my timeline. Coding in those days really was like: You know what your compiler will generate as machine code while you type in C.
Sure it was possible to do it better in assembler. You always fond c programming coursework help tricks to beat your compiler. You knew when and how often loop unrolling would make sense. But at what cost? You sure would not code a REPL that way just to wait faster for user input.
We are driving full throttle against a complexity wall. So, Xilinx has this crappy tiny softcore processor for their FPGAs PicoBlaze. It has C syntax. The Python script literally just translates it flat-out into assembly. plus other restrictions, obviously. Suddenly, all the complaints vanished, and people were easily able to find dumb logic bugs in stuff I wrote.
They learn a system or rigid rules and symbols instead of the principle, because it takes less energy to memorize and repeat than to understand and apply.
