Modeling micro-controller peripherals for high-level co-simulation and synthesis
Abstract:
Mapping a behavior on an embedded system involves hardware-software
partitioning and assignment of software and hardware tasks to different
components. In particular, software tasks in embedded controllers
are mostly assigned to a micro-controller. However, some
micro-controller peripherals
are implemented with partly programmable components that can be regarded
as very simple co-processors with limited instruction sets and
capabilities. Embedded system designers are used to mapping
some simple software tasks onto these simple co-processors, obtaining
overall performances that can be orders of magnitude superior
to the ones obtained mapping all software tasks to the micro-controller itself.
In this paper,
we propose a methodology to specify, simulate, and partition tasks
that can be implemented on programmable micro-controller peripherals
such as Timing Processing Units (TPUs).
Following our general philosophy, we let the designer propose
a partition, and we provide
an environment
- to efficiently simulate and
evaluate a particular implementation choice
- to automate downstream
synthesis for software, hardware, as well as peripheral programming routines.
