Emerging mobile devices are likely to adopt CPU-GPU heterogeneous architecture where an embedded GPU executes offloaded computations from the CPU as well as rendering tasks. For design space exploration of such a CPU-GPU heterogeneous architecture at the early design stage or for monitoring the dynamic system behavior of a system, it is very desirable to(More)
H.264/AVC video encoders have been widely used for its high coding efficiency. Since the computational demand proportional to the frame resolution is constantly increasing, it has been of great interest to accelerate H.264/AVC by parallel processing. Recently, graphics processing units (GPUs) have emerged as a viable target for accelerating general purpose(More)
Multi-core CPU/GPU heterogeneous platforms became popular in embedded systems. A full system simulator is typically used to observe the internal system behavior by running complete software stacks without modification on simulation models of CPUs and other devices in the system. However, there are few known full system simulators for CPU/GPU heterogeneous(More)
