You might remember my musings with the XOR gate with interlocked NPN transistors discussed at Bipolar XOR gate with only 2 transistors But thinking about how XOR is done with pass transistors in CMOS and the structure often creates a MUX, I wondered...
Edit: See also More 2369, with more caps !With a sporadic and limited access to the workshop (at last !) I can finally try new ideas ! I have meanwhile received 9K PMBT2369 in SMD but I decided to use the old stock of 50pc 2N2369A in metal can, that...
Note: this log is obsoleted by BitsliceAfter the last log Adder with Falstad, I also converted the ROP2 bitslice to the interactive simulator : There is still the challenge to disable the output of the CLA so it can be combined by ORs with the rest...
One last thing that was still missing was the symbol table. Apparently the output of the softmax layer maps directly to the symbol table, and since this output is 128 in length, I was searching for a table of this same length.The prime suspect was of...
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....
SATA StatusAfter weeks of painful debugging. I have been able to read and write to the hard drive!I ran into an issue though... the speed at which I can communicate with my FPGA to/from my computer maxes out at about 16MBs and the hard drive reads/writes...
Stephen : Alright, let's get rolling. A BIG hello to @Parker for joining us today Parker : Howdy everyone Stephen : @Parker, why don't you kick this off by giving us an introduction of who you are, what you do, and what...

Hello, everyone we thought it was time for a complete log since the two previous ones were quite small. Please, take note that that you can now find the Source Code in the shared files and that the components list has been updated too. Let’s look at...
The ROP2 and ALU part has been slowly expanding to the SUXEN but the log 70. The nexus reminds that something is missing : I have forgotten to include PC+1 (NPC) value. So another level of MUX is required, which is fortunate because I had...
Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...
