Few addressing modes, fix instructions formats

Higher clock cycle per second

Complex design of a compiler

Processors now operate at a clock frequency of 2 MHz.

Earlier generation microprocessors’ fetch–and–execute
cycle was guided by a clock frequency of order of 1 MHz

A microprocessor is a single VLSI chip having a CPU

A .... is a single–chip VLSI unit

is also called as microcomputer

Single task oriented

RAM,ROM, I/O ports, Timers can be added externally and can vary in numbers

.... is cheaper than ....

.... consumes less power & space

Enbedded System software is normally written in a high–level language and then compiled
down to offer code that can be mounted within a volatile memory in the hardware.

The software should consider three limits which are system
memory, processor speed, and power consumption

Use of ...... has some
distinct advantages over ........ codes–low
development time, shorter debug cycles and ease of maintenance

In Mix mode programming, both the “C” & “C#”
language are used for application development.

RTOS supervises the application software and provide
mechanism to let the processor run a process as per
scheduling by following a plan to control the latencies.

RTOS sets the rules during the execution of application
program.
and It is responsible for managing the different hardware resources of Embedded system

we can classify embedded systems as real time, stand alone, networked, mobile based on
