OpenOFDM - implementation of 802.11 OFDM decoder.

In a nutshell, the top level dot11 Verilog module takes 32-bit I/Q samples (16-bit each) as input, and output decoded bytes in 802.11 packet. The sampling rate is 20 MSPS and the clock rate is 100 MHz.

Features:
◦ Full support for legacy 802.11a/g
◦ Support 802.11n for MCS 0..7@20MHz bandwidth
◦ Cross validation with included Python decoder

USB3 PIPE interface for Xilinx 7-Series / Lattice ECP5

Current solutions for USB3 connectivity with an FPGA require the use of an external SerDes chip (TI TUSB1310A) or external FIFO (FTDI FT60X or Cypress FX3). With this project, we want to see if it's possible to just use the transceivers of the FPGA for the USB3 connectivity and have the USB3 PIPE directly implemented in the fabric (and then avoid any external chip).

BOOM - an open-source out-of-order RISC-V CPU (RV64G ISA).
Like most contemporary high-performance cores, BOOM is superscalar (able to execute multiple instructions per cycle) and out-of-order (able to execute instructions as their dependencies are resolved and not restricted to their program order).

The main features of BOOMv2:
◦ updated 3-stage front-end design with a bigger set-associative Branch Target Buffer (BTB)
◦ pipelined register rename stage
◦ split floating point and integer register files
◦ dedicated floating point pipeline
◦ separate issue windows for floating point, integer, and memory micro-operations
◦ separate stages for issue-select and register read

This library has many of the standard components that you use in hardware design. But these ones are nicely parameterized, and try to use latency-insensitive
interfaces where it does not hurt performance.
