<p>A portable electronic device (60) may include the power management system in accordance with the invention. In this embodiment, the device shown has been implemented as a two-processor system of a chip, but the power management system is applicable to any type of electronic device. The system may also include a cross bar multipath memory controller (62) and cross bar multipath peripheral controller (64). The multiple processor system (60) may include a host processor (66) which may preferably be a reduced instruction set (RISC) ARM core and coprocessor core (68) that operate in a cooperative manner to complete tasks as described above. In the preferred embodiment, there may also be a hardware accelerator engine (70) as shown. A software DMA engine (71) in this preferred embodiment may be executed by the coprocessor core (68).</p> |
