I'm doing this project called "High data rate logger".
The requirements for this project is to sample the 2 analog signals simultaneously.
- 2x channel 14-bit ADC
- Store 60 MSps (mega samples per second), which is roughly 250 MBps sustained write speed
- Storage medium must be able to accommodate 500 GB to 1 TB worth of data
M.2 PCI-Express is the latest interface for SSDs (solid state drive). But I am not sure if I can interface an SSD to FPGA through PCIe 2.0 x4 (PCI express generation 2, with 4 lanes) Interface, because of its complications.
A host that can interface with the above cards:
Since I am not able to find a processor which has parallel LVDS input lines to be interfaced to ADC, I am thinking to proceed with an FPGA.
But at the other end I have to interface a storage medium like SSD,or SD cards, or NAND flash memory or any other possible solution.
There are many solutions for storage medium with required memory as well as speed. But the problem is interface. Some common memory interfaces are: PCI express, SATA III (6Gbps), SD card interface, etc.
Therefore I would request anybody to suggest which interface would be feasible, easier and better to interface using FPGA.
If an appropriate standard interface is selected, I could go ahead with selecting an FPGA and designing a data logger.
