Event driven embedded systems are one of the essential structures of heterogeneous embedded systems. The difference behavior of hardware and software motivates the usage of high-level system design approaches such as Hardware Software co-design Model
. The objective of this paper is to obtain a new Co-design model for discrete-events embedded systems based on Markov chains, and then using the heterogeneous modeling by composing the discrete-times model within discrete-events model to apply it on anti‐lock braking system (ABS). To achieve the model, we use Ptolemy II which is a Java-based software framework developed as part of the Ptolemy Project by University of California, Berkeley. The importance of this paper is to be the kernel for heterogeneous co-design modeling for heterogeneous embedded systems in future works.
Considered response times in most systems is the basic
criterion for assessing the performance and seeks developers to
lose wait to meet the required operating time.
In this research, were compared response times to customer
requests from servers
with different specifications with the server
has been designed and implemented using embedded systems
where the customers request video or audio files stored in an
external large storage, through a local computer network, and so
at the lowest possible cost compared to the huge servers that
perform the same purpose, and power consumption is very low.
And we got in our system response times to customer requests
for less than the response times to requests applied to large
servers dedicated just to meet the customers without any
additional services of time periods from the rank of micro
seconds.
