on-chip (SoC).

The firmware is a working example of how to interface to the hardware, collect samples, and save them to memory. Figure 3

shows the process flow. The firmware is written in C using the Xilinx SDK tool, which is based on the Eclipse open source

standard. Custom Petaluma-specific design functions were created utilizing the AXI MAX11046 custom IP core. The firmware

supports the maximum ADC sampling rate at 250ksps.
