Abstract :
Handheld devices are expected to start using fine-grained ASIC accelerators to meet energy-efficiency requirements of increasingly complex applications, e.g., video decoding and reconfigurable radio. To avoid overhead, static multiprocessor schedules are preferable for orchestrating fine-grained accelerators. However, as modern applications use accelerators in irregular patterns, static scheduling leads to low hardware utilization.
