System On Chip Breakpoint Methodology (US 8656221)
A system-on-chip (SoC) with a debugging methodology. The system-on-chip (SoC) includes a central processing unit (CPU) and multiple computing elements connected to the CPU. The CPU is configured to program the computing elements with task descriptors and the computing elements are configured to receive the task descriptors and to perform a computation based on the task descriptors. The task descriptors include a field which specifies a breakpoint state of the computing element. A system level event status register (ESR) attaches to and is accessible by the CPU and the computing elements. Each of the computing elements has a comparator configured to compare the present state of the computing element to the breakpoint state. The computing element is configured to drive a breakpoint event to the event status register (ESR) if the present state of the computing element is the breakpoint state.
