System Memory XMC Daughtercard
The system memory XMC daughtercard provides either 2 GB or 4 GB of DDR SDRAM for signal and image processing applications with intensive data streaming requirements. It can be plugged into a single RapidIO® XMC site on a carrier board to easily add large amounts of memory to the system configuration. A sufficiently large input or output buffer can be important for optimizing system performance in stream computing applications. Application software can access the memory through its embedded high-performance RapidIO interface, which includes a DMA engine for command chaining and corner turning. The memory provides access at full-duplex data rates of up to 622 MB/s in Mercury processing systems.
Features
- Integrated RapidIO memory node
- Up to 4 GB with 622 + 622 MB/s full-duplex transfers
- Advanced DMA engine for chained sub-matrix moves
- VITA 42.1 XMC with RapidIO
Benefits
- Extra memory storage close to processors with access speed approaching local memory
- Reduces total compute time, arbitration, and overhead to maximize overall system performance for systems with unrelenting, high-bandwidth data streams
- Includes error detection and correction
Specifications
Commercial/Environmental Specifications Operating temperature: 0°C to 40°C at 10,000 ft
(Inlet air temperature at the carrier board's recommended minimum airflow)
Storage temperature: -40°C to +85°C
Relative humidity: 10-90% (non-condensing) As altitude increases, air density decreases; hence, the cooling effect of a particular number of CFM decreases. Many manufacturers specify altitude and temperature that are not simultaneous. Note that the above operating temperature is specified simultaneously with an altitude. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Electrical and Mechanical Specifications Power consumption:
1.3A at 5.0V (max operating)
1.1A at 5.0V (standby)
Dimensions: 2.9 in x 6.5 in (including bezel)
