It has been one of the most fundamental challenges in architecture design to achieve high performance with low power while maintaining flexibility. Parallel architectures such as coarse-grained reconfigurable architecture, where multiple PEs are tightly coupled with each other, can be a viable solution to the problem. However, the PEs are typically controlled by a centralized control unit, which makes it hard to parallelize programs requiring different control of each PE. To overcome this limitation, it is essential to convert control flows into data flows by adopting the predicated execution technique, but it may incur additional power consumption.
