+At least 7 open source implementations:
 
  * Rocket chip: Simple in-order processor
  * BOOM and BOOMv2: OOO Superscalar processor
  * PicoRV32
+ * Two Western Digital processors
  * Two educational implementations that I won't talk about today
 
 Rocket is the most widely used.  It is written in Chisel which is a
 Scala-based metalanguage that generates Verilog.  PicoRV32 is a lot of
 fun too: It's written in Verilog and can be programmed on to a very
-cheap (under $40) FPGA.

 Bootstrapping Fedora is complicated: I started off with an x86-64 disk
 image which could run rpmbuild.  I then removed all of the x86-64
 binaries and libraries.  I replaced them with cross-compiled RISC-V

 While we were working on Fedora, we were also working closely with the
 Debian and upstream communities.  Patches and techniques are shared
 with upstream and with Debian.
