If so… The potential market size is approximately 35 million units per year.The University of Texas at AustinEE 382V Class NotesFoil # 5 What problem are we trying to solve?  There is a need to transmit and receive digital music and data using existing long-, medium- and short-wave transmission systems. Transmitters in these wavelengths are accessible world wide. Need to provide near-FM quality sound and the capacity to integrate data and text.The University of Texas at AustinEE 382V Class NotesFoil # 6 Competition Texas Instruments currently offers the TMS320DRM300/350 component:The University of Texas at AustinEE 382V Class NotesFoil # 7 Agenda What is in a MRD Market Focus Product description Cost Metrics  Product Features ReferencesThe University of Texas at AustinEE 382V Class NotesFoil # 8 Product description You will generate a PRD for a DRM IP sub-system that can be integrated into a MP3 player or a 4G cell phone. The hardware intellectual property will be delivered in the SystemCtools environment. This will include all components which are not available in the standard library, such as accelerators, special I/O devices, etc.The University of Texas at AustinEE 382V Class NotesFoil # 9 Product Benefits A DRM system provides the following benefits: Ability to receive digital music and data using existing long-, medium- and short-wave transmission systems providing near-FM quality sound available to markets worldwide. DRM has a small bandwidth of less than 20 kHz – easy to handle with current generation of embedded computing devices.  The quality of DRM audio is excellent, and the improvement upon analog AM is immediately noticeable. DRM can be used for a range of audio content, including multi-lingual speech and music. The University of Texas at AustinEE 382V Class NotesFoil # 10 Product Benefits (cont’d) A DRM system provides the following benefits: Besides providing near-FM quality audio, the DRM system has the capacity to integrate data and text. This additional content can be displayed on DRM receivers to enhance the listening experience.  Unlike digital systems that require a new frequency allocation, DRM uses existing AM broadcast frequency bands. The DRM signal is designed to fit in with the existing AM broadcast bandplan, based on signals of 9 kHz or 10kHz bandwidth. It has modesrequiring as little as 4.5kHz or 5kHz bandwidth, plus modes thatcan take advantage of wider bandwidths, such as 18 or 20kHz.The University of Texas at AustinEE 382V Class NotesFoil # 11 Agenda What is in a MRD Market Focus Product description Cost Metrics  Product Features ReferencesThe University of Texas at AustinEE 382V Class NotesFoil # 12 Cost Metrics Performance Utilize no more than 75 MHz of an ARM 926-EJS running at 256 MHz Additional die size cost Accelerators .5 mm2 On board Memory - TBD Advanced System and Power Management  Additional system power for accelerators: < 8 mWThe University of Texas at AustinEE 382V Class NotesFoil # 13 Agenda What is in a MRD Market Focus Product description Cost Metrics  Product Features ReferencesThe University of Texas at AustinEE 382V Class NotesFoil # 14 Product Features Flexible and scalable platform based architecture. Standard architecture for a wide range of devices supporting a wide range of information services Flexibility – To be able to dynamically re-program different waveforms tailored to particular scenarios Portability – To be able to host third party designs on multiple independent platforms Potential for significant life-cycle cost reduction Over the air downloads of software patches, and new features and services Offers significant improvement in flexibility, portability and interoperability between different usersThe University of Texas at AustinEE 382V Class NotesFoil # 15 Product Features (cont) Frequency coverage 0-32 MHz Mode reception: USB, LSB, CW, AM, synchronous AM, NFM, DATA Advanced IP3 greater than +35 dBm Very high dynamic range >100 dB in AM mode with 7 kHz filter >105 dB in SSB mode with 2.2 kHz filter >110 dB in CW mode with 500 Hz filter Passband tuning +/-5 kHz Audio pitch tune in CW & DATAThe University of Texas at AustinEE 382V Class NotesFoil # 16 Agenda What is in a MRD Market Focus Product description Cost Metrics  Product Features ReferencesThe University of Texas at AustinEE 382V Class NotesFoil # 17 References DRM Consortium http://www.drmrx.org/ http://www.drm.org/ PC based software for DRM reception user manual  http://www.drmrx.org/downloads/docs/drm_sw_radio_manual_V1_3.pdf WINRADiO info
