Ragon Systems is expert in delivery high quality hardware and software products in embedded systems like 8051 development boards, Atmega development boards, PIC development boards, security alarms, home automation systems, safety systems etc.
Engineering students generally faces problem in getting right knowledge about how to design and develop embedded systems or learn about embedded systems projects. Ragon Systems will be right choice for everyone interested in learning about embedded systems.
An embedded system is a one that has computer hardware with software embedded in it as one of its important components.
Computer hardware like microprocessor, memory, input units, output units, network units are embedded systems.
Components of an embedded system are hardware like processors, interrupt controller, memories, ports etc; it has main application software which may perform concurrently the series of tasks. It has real time operating systems which defines the system works. RTOS supervises the application software. It sets the rules during the application program. But a small scale embedded systems may not need RTOS.
Embedded systems are designed keeping in view the following three constraints available system memory, available processor speed, and the need to power dissipation.
Real time operation, size, cost, time, reliability, safety, energy, security makes embedded systems different.
Embedded system can be classified into small scale embedded system, medium scale embedded system, sophisticated embedded system.
Small scale embedded system uses single 8-bit or 16 bit microcontroller and usually ‘C’ is used for developing the system.
In medium scale embedded system, single or few 16 bit or 32bit or digital signal processors (DSP) or Reduced Instructions Set Computers (RISC).
C has full the software industry by tempest. In the last few years even the microcontroller industry, the last support of pure assembly language, has qualified an exponential use of C language programs.
C's rapid explosion spawned dozens of compilers besieged to embedded systems. Their superiority ranges from nearly wonderful to complete unfeasible. Sometimes the compiler's ability is inversely proportional to the data sheet's gloss and the product's cost. Unfortunately the best distinctiveness are noticeable in the vendor's advertising, the worst don't show up until you've used it for some time.
Code size and speed are usually highest programming concerns, particularly to pessimistic dyed-in-the-wool assembly programmers being dragged into a high level language for the first time. I be uncertain to add to the publicity about efficiency, except to state the clear, that C code is slower and larger than comparable assembly. But not by much - in most cases the distinction is only about 25%.
It's firm to beat C for a large embedded project. Everybody admits that it is less competent than assembly, but C will decrease non-recurring engineering costs by a factor of 3 or more. In most products the investments in design, coding and maintenance quickly justify the extra memory expenses.
This conservative wisdom doesn't directly apply to microcontrollers, where ROM sizes are fixed and just can't be augmented. Still, the superiority of modern compilers is such that the price in memory space for using C is small. Using a controller with a little extra memory can save a lot during development.
