Paper Abstract

The paper presents a design for a High-Density Solid-State Data Recorder (HDR), commercially known as the Tornado 2HD, for use in Reconaissance and High-Speed Sensor Data Acquisition applications. The HDR has the capacity to record data in excess of 5.0Gb/sec sustained via a proprietary Low-Voltage Differential Serial (LVDS) interface and employs an open-architecture VMEbus front end. Allowing data input and archiving through a myriad of standard PMC (PCI Mezznine Card)-based interfaces (SCSI, Fiber-Channel, USB, etc.). A dedicated DCRSi240 interface is also included to allow archiving of data to compatible tape recorders. Solid-state memory is composed of 512Mb EEPROMs arranged as a Removable Memory Unit (RMU) modules of eight memory cards, with each card providing 13.82GB of data storage, for a total of 110.2GB per module. Memory is expandable in .3GB blocks and is theoretically limited only by space and total power requirements of the recorder, since all data and control signals are synchronously redriven between memory cards and RMUs. Erase, read, and write operations for each memory card are controlled autonomously by a single Matrix Array Controller (MAC) FPGA mounted on the card. Recorder user interface is provided by a VME-based dual PowerPC Single-Board Computer (SBC) with control provided via RS-232, DCRSi240, or Ethernet interfaces. The VME front end also provides standard capabilities, such as IRIG-B, Digital I/O, SCSI, and other PMC-based interfaces.
