Interfacing Cypress MoBL Asynchronous Dual-Port to TI OMAP1710 Multimedia Processor
The Texas Instruments OMAP1710 Multimedia Processor is a low-power, highly-integrated hardware and software platform designed to meet the application processing needs of next-generation embedded devices.The OMAPTM platform enables OEMs and ODMs to quickly bring to market devices featuring rich user interfaces, high-processing performance, and long battery life through the maximum flexibility of a fully-integrated mixed-processor solution.The OMAP1710 is primarily targeted at mobile communications applications using WLAN802.11x, Bluetooth, GSM, GPRS, EDGE, CDMA and other proprietary wireless standards. The processor provides video and image processing (MPEG, JPEG, etc.), advanced speech/audio processing, graphics and video acceleration, generalized web access and data processing.The OMAP1710 Multimedia Processor supports External Memory Interface (EMIF) that readily connects to Cypress asynchronous Dual-Ports. This application note describes the wiring, EMIF register settings, and other design considerations for connecting the OMAP1710 Multimedia Processor to the 1/4 Mb Cypress MoBL(TM) Dual-Port (CYDM256A16-55). The same design can be used in interfacing the OMAP1710 Multimedia Processor to other Cypress MoBL Dual-Ports in the x16 configuration, such as the CYDM128A16 and CYDM064A16.
