The LDS SATA RECORDER XK7 IP is a complete recorder sub-system IP. It can be configured according to the recording performance required and the quantity of the data to be recorded.
– The data can be recorded in FAT32 or in RAW format. In FAT32 mode, the disks must be already formatted or can be formatted through the Ethernet link and a PC under windows or Linux (free driver).
– The Ethernet link, when used, enables to download FAT32 files into your PC to process them later according to user application (It is not used to record data).
o 1Gbits LDS Mac in GMII or 10Gbits Ethernet LDS Mac with XGMII, XAUI or SFP+ interface.
o Manages jumbo frame until 9216 bytes
o Manages AoE protocol in State Machine
– The ‘Generator_Checker’ block enables to check any recording error in the data flow. This block generates a counter which is written into disks and then readback and compared in order to detect any recording error. The user data goes through this block with the help of asynchronous internal FIFO.
– A User Interface on a Hyperterminal enables to configure all the recording session (recording size, file size, raid0 strip, number of disk, Directory, etc…) and enables to run a write and read performance test of the system using the ‘Generator_Checker’ block. It enables you to check the performance of your systems, especially the disks.
Netlist and VHDL source code format is available for ease of customization. The C source code is always provided. It can be customized by Logic Design Solutions.
