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.
