eP32 on LatticeXP2 Brevia Board, Part II - CH Ting
The ispLEVER development system from Lattice includes the tool suite REVEAL, which allows one to synthesize a logic analyzer with the core in the FPGA. This logic analyzer can then be used to trace any internal signal in core while it is running. Ting will discuss ispLEVER, REVEAL, and eP32. He will release an evaluation version of eP32 on XP2 to those who have a Brevia Board.

On Forth Day, eP32 Forth on Ting's Brevia Board would not restart when the reset button was pressed. Using these Lattice utilities, Ting found that this was due to the strange behavior of the onboard RAM memory: Memory 0 worked fine with a reset vector, but Memory 1 always returned bogus data.

DocForth - a Forth Pretty Printer - James Bowman
DocForth's aim is to make Forth sourcecode easier to understand: definitions are in bold, each compiled or interpreted word links to its definition, and ANS Forth words link to their definition in the standard.

Gforth Overview - John E. Harbold
John was ill and could not give us a look at Gforth's capabilities. His talk will be rescheduled for January.
