High Speed Embedded Memory

Hello guys,

We are in process of designing a new embedded high performance data acquisition platform. Basically, we have let’s say 400 ADC channels which each channel is 16 bit wide and we need to sample these channels at 50Khz frequency which generates almost 40MB of data per second. We need to store this data in order to be downloaded later on. The amount of data which we need to store is about 20 GB of data. We don’t have any problem with buffering this data as we implemented multiple NiosII processors with multiple SGDMAs. However, the only bottleneck of the system is storage memory. We need a device which capable of storing this data. It should be noted that this device should be reliable one and also can operate at extended temperature ranges. Any idea and recommendation on that would be much appreciated. Also, I should mention that this tool is a remotely controlled and battery operated tool.

Regards,

Aidan.
