The OMAP5910 device from Texas Instruments (TI) has a new dual-core architecture that is optimized for multimedia applications in a low-power environment. It couples two processorsa TI-enhanced TI925T general-purpose processor and an ultralow-power TMS320C55x™ (C55x™) digital signal processor (DSP)with a rich set of peripherals and powerful interfaces to achieve optimal performance.
Within the OMAP5910 device, the C55x DSP can use its memory management unit (MMU) to access the DSP external memory space. This application note discusses the basic DSP MMU architecture and the benefits of using an MMU. It also explains how the DSP MMU is programmed and provides programming examples.
