....required, e.g. in the presence of relative timing constraints among hardware tasks. We further assume that some dynamic scheduling is required to handle inexact execution delays, which are certainly present in software tasks, and conditional execution of tasks. The run time scheduler synthesis of [17, 18, 19] assumed that no conditional execution of tasks would occur. Our tool, called Clara2, automates the addition of conditional edges to the original control ow of hardware and software tasks in order to satisfy resource constraints while minimizing worst case execution time (WCET) for the ....
.... gravity sum vector matrix vector multiply matrix vector multiply forward kinematics Figure 1: Robotics Example: Concurrent Control Laws 2 Task Modelling The research here builds on previously reported results; thus, in this section, we brie y summarize the task modelling approach of [16, 17, 18, 19]. Tasks are speci cied in Verilog or C, with one of the tasks designated as the main task. The main task begins execution and calls the other tasks. The main task speci es the overall sequence of tasks in the application (an example of a main task can be seen in Figure 2) From the main task we ....

....of storage elements (registers or data memory) accessed by a task during the task execution. On the de nition of task we set no restrictions. A task can be a simple function, a star or a galaxy in Ptolemy[4] a CFSM (Codesign Finite State Machine) in POLIS [5] a real time task described in [15], or an object consisting of a variable set and methods in [27] 25] From the implementational point of view, we specify a task as a (set of) code segment(s) in SW (SW task) or a set of components in HW (HW task) The basic idea of task based state saving (TBSS) method is to store only the states ....
