    4 This BSP is for the [http://www.gaisler.com/products/leon3/leon3.html LEON3 SPARC V8 processor] developed by [http://www.gaisler.com Aeroflex Gaisler]. LEON3 is available as a synthesizable VHDL model, allowing custom implementations on FPGA and/or ASIC. The LEON3 BSP probes AMBA Play&Play information for basic peripherals such as interrupt controller, timer, and UART. Probing the Plug&Play makes it possible for the LEON3 BSP to supports many LEON3 based controllers and boards. The LEON3 BSP has also support for the LEON4. The basic peripherals:
