  This paper presents the research work on multicore microcontrollers using
parallel, and time critical programming for the embedded systems. Due to the
high complexity and limitations, it is very hard to work on the application
development phase on such architectures. The experimental results mentioned in
the paper are based on xCORE multicore microcontroller form XMOS. The paper
also imitates multi-tasking and parallel programming for the same platform. The
tasks assigned to multiple cores are executed simultaneously, which saves the
time and energy. The relative study for multicore processor and multicore
controller concludes that micro architecture based controller having multiple
cores illustrates better performance in time critical multi-tasking
environment. The research work mentioned here not only illustrates the
functionality of multicore microcontroller, but also express the novel
technique of programming, profiling and optimization on such platforms in real
time environments.
