Time-constrained Design of Pipelined Control-intensive Systems

چکیده
Although there are widely known solutions for dataflow-dominated resource constrained high-level synthesis (HLS) problems, optimization of hardware resources under time-constraints in controlintensive systems is still a challenge. This paper examines the case when functional pipelining is used to increase the throughput of the system. The traditional concept of mutually exclusive conditional branches must be dropped and new methods are needed to exploit the resource sharing possibilities of conditional branches. We developed new methodologies able to exploit the resource sharing possibilities under these circumstances and extended the two schedulers and the allocation module of the HLS tool PIPE to handle arbitrarily nested conditional structures and demonstrated the improved resource utilization on control-intensive benchmarks.

The Exact Solution of Min-Time Optimal Control Problem in Constrained LTI Systems: A State Transition Matrix Approach
In this paper, the min-time optimal control problem is mainly investigated in the linear time invariant (LTI) continuous-time control system with a constrained input. A high order dynamical LTI system is firstly considered for this purpose. Then the Pontryagin principle and some necessary optimality conditions have been simultaneously used to solve the optimal control problem. These optimality ...
