| Abstract | Energy-efficient user-interactive and display-oriented ap-plications on handhelds rely heavily on multiple accelerators (termed IP cores) to meet their periodic frame processing needs. Further, these platforms are starting to host multiple applications concurrently on the multiple CPU cores. Unfor-tunately, today’s hardware exposes an interface that forces the host software (Android drivers) to treat each IP core as an isolated device. Consequently, the host CPU has to get involved in the (i) processing of each frame, (ii) scheduling them to ensure timely progress through the IP cores to meet their QoS needs, and (iii) explicitly having to move data from one IP core to the next, with main memory serving as the common staging area.
