Fiber Optic Gyroscope

Customer hired LSF Design to design several aspects of a fiber optic gyroscope (FOG). We implemented two FPGA's and several board designs in a stack of boards that comprised a FOG and IMU assembly. The first FPGA is a part of the FOG loop itself. Running 3-channels concurrently the FOG FPGA closes the FOG control loop and sends data to the IMU FPGA. The IMU FPGA interfaces with the other sensors in the system - accelerometers, temperature, current & voltage correlates that data and forwards it to a TI DSP that runs a Kalman Filter. LSF coded the FPGA testbench designs, the FPGA RTL, designed the PCB schematics and performed the PCB layout for several circuit boards. LSF supported the customer system bring up and integration.

Baggage Scanner

Customer hired LSF Design to design two FPGA's as a part of a CT-scan baggage scanner. The first FPGA lives in the spinning gantry portion of the scanner. This part received data from multiple X-Ray sensors, aggregated it and drove a serial stream across a slip ring to the second FPGA. The second part received the serial stream, decoded it, stored frames in a local memory and then DMA'ed frames into a common ring buffer built in system memory. LSF was responsible for the design, simulation and implementation for both parts.

Commercial Oven Controller

LSF was hired to architect, write and implement the DSP code for a commercial oven control module. The code for the Hercules DSP from Texas Instruments was written in C, implemented and tested using Code Composer Studio. LSF was responsible for the code, testing, documentation and to be IEC60730 Class C compliant.

Custom Interface Board

Customer required a custom interface board design to tie together multiple modules. This board needed to break out the IO for high speed communication channels as well as include a battery monitor and recharging circuit. LSF compiled a specification to the interfaces and designed the circuits. We performed the board layout and built a prototype run for the customer delivering debugged boards.

PCIe Interface for Encryption Engine

LSF was hired to design and implement a PCIe interface, a CSR block, overall top level chip design and testbench for a cryptographic engine FPGA. Our role on the team was to work with the customers engineers to tie together several disparate design modules, implement and test them in simulation. We were also the key interface with the software group in developing the driver for the board and assisting in system integration debug.
