In computer science, bare machine or bare metal refers to a computer executing instructions directly on logic hardware without an intervening operating system.
Increasing the speed of execution of the program consequently increases the speed of the processor. There are many ways invented, both hardware implementation and Software architecture, to increase the speed of execution. It was observed that by executing instructions concurrently the time required for execution can be reduced. The concept of Parallelism in programming was proposed.
What are advantages and disadvantages of embedded operating system
Difference between C language and Embedded C. First of all, the brief introduction and history of language C and Embedded C. We always use c language on processor which has operating system install on it. Its mean c language is designed to run systems which has high memory. But embedded is particularly designed to run on microcontroller based application. So we can get an idea that c language execute on system which have high resources unlike embedded c which runs on microcontrollers which has limited resources like RAM, ROM and program memory.
When we compile c program it is operating system dependent file which compiler generate but embedded c code execute on microcontrollers only. PIC16FA is major microcontroller of microchip. C is basically a general purpose, vital important high level programming language that is best for firmware developing and the application used for portable purposes.
It supports to improve the quality of computer programming and for solving the problems in a small amount of time. It is procedural language and was designed for complied using very useful compiler to feed a very low level memory. Using complier c language is converted into machine level language. It is useful for many applications, such as application in which is code writing is so much difficult by using c that code can be easily develop.
It was developed by Dennis Ritchie in between and at bell labs for operating system Unix. Embedded c is actually the extension of c language. It consists of c language sets that can be used for different purposes. It was extending by the standard committee c in for solving the issues provide by c language.
It mostly used the syntax and standard c semantics. This language has so many features as compared to c language such as it used the fixed point arithmetic, spaces between maned address and hardware input, output addressing. As we look around ourselves, we have so many embedded systems such as washing machine, digital camera and mobile phones all these the examples of embedded system, in all these things embedded c language is used. So many extra characteristics have added in embedded c such as operation or mapping register, number of memory area and representation of fixed point.
So if we only talk about programming then the programming of language c and embedded c is almost same only lies the difference between these two is the resources how we use it and some kind of code effectively.

Microprocessor Advantages & Disadvantages
Multithreading and multicontexting are powerful tools for enhancing the performance of BEA Tuxedo applications-given the appropriate circumstances. Before embarking on a plan to use these techniques, however, it is important to understand potential benefits and pitfalls. Improved performance and concurrency For certain applications, performance and concurrency can be improved by using multithreading and multicontexting together. In other applications, performance can be unaffected or even degraded by using multithreading and multicontexting together. How performance is affected depends on your application. Simplified coding of remote procedure calls and conversations In some applications it is easier to code different remote procedure calls and conversations in separate threads than to manage them from the same thread. Simultaneous access to multiple applications Your BEA Tuxedo clients can be connected to more than one application at a time.
An Operating System performs all the basic tasks like managing files, processes, and memory. Thus operating system acts as the manager of all the resources, i. Thus, the operating system becomes an interface between user and machine. Types of Operating Systems: Some widely used operating systems are as follows-. There is an operator which takes similar jobs having the same requirement and group them into batches.
Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. Modern embedded systems are often based on microcontrollers i. In either case, the processor s used may be types ranging from general purpose to those specialized in a certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor DSP.
Before we learn Embedded System, lets learn: What is a System?
Если Цифровой крепости суждено стать любимой игрушкой АНБ, Стратмор хотел убедиться, что взломать ее невозможно. - Ты по-прежнему хочешь уйти. Сьюзан посмотрела на. Сидя рядом с великим Тревором Стратмором, она невольно почувствовала, что страхи ее покинули.
Ты в опасности. Казалось, она его не слышала. Хейл понимал, что говорит полную ерунду, потому что Стратмор никогда не причинит ей вреда, и она это отлично знает.
АНБ, - подумал. - НБ - это, конечно, не болтай. Вот такое агентство.
- Звук его голоса гулко раздался в комнате оперативного управления, и все тут же замерли, повернувшись к экрану. - Сьюзан Флетчер, выйдете за меня замуж. В комнате зашушукались.
