Microcoding as a technique is very much aligned with "test-driven development" concept. Essentially it means first to build the scaffolding needed to test the circuit, and then the circuit itself. Just like the microcoding itself, the advantage here...
Summary Just exploring some Docker basics, with a bent towards Raspberry Pi when relevant. Deets The path to here is long and tortuous. Multics. Unix. VAX. 386. V86 mode. chroot. Solaris Zones. cgroups. LXC. and now, Docker. The concept is similar...
The heart of Think-a-Tron 2020 consists of three main parts: the camera QR code reader section, the display, and the question (?) console with speaker. The ESP32-CAM is mounted in a rectangular box forming the main part of the core section. You can see...
Following the previous log An individual job and all the necessary processing, I wrote the program gold_01.c to check the behaviour before I increase parallelism. First thing it did was confirm that the result C=1 occurs only when the result X=0. So...
well.... this page suggests absolute-addressing does some funky stuff... http://jgmalcolm.com/z80/variables/abso The table suggests RAM starts at 0x0c000 (which is where the first page is always "mapped"), but, thereafter continues unbroken (in 24bit...
The TI-86 is very hacker-friendly... Aside from being designed with users' custom assembly/machine-code/binary-executables in mind, there are also quite a few openings for hardware-hacks. I did some testing and discovered that there are 20 accessible...
Brief (yeah, right...) recap... What I need is a somewhat-accurate reading of the CPU frequency so that I can bitbang a bidirectional UART. This differs from my previous "UARto[S]T" (Universal Asynchronous Receiver to [Synchronous] Transmitter),...
Well, I got some new-shineys! So, this project has wound-up on hold... Briefly: In my life"style" power is a huge concern, as is space. Thus I've been fighting (for years, really) to figure out a decent and reliable solution to the problem of having...
The library / class has most of the functionality I want, but it's a bit of a mess. Time to do some rearranging, shuffling around of variables and functions. Throw away that one flag that's not been used for a while. Put all declarations back in place...
The calculator/CPU cannot function on its own, without being embedded in a system that gives it the I/O, clock, outside hardware connections etc. on the FPGA board. The top-level object that does this is sys_sbc8816.vhd (simplified schema, bolded...
Back in the early 2000's I had a project which went quite smoothly, until suddenly, and for months, eluded the heck out of me, and still that bit haunts me to this day. Prior to that project, I'd been doing stuff with AVRs for years, fancied myself pretty...
It is Wednesday my dudes² 16:53 07/12/2022 So, let's try again, and this time I wll make a list of what I want to calculate first, so I don't just give up on writting this damn thing: Calculate the force generated by the High displacement...
Wednesday, 13/09/2023, 12:13 I'm feeling like whatever the hell I wrote in these "serious" project logs are complete nonsense, not only because I'm talking things with almost no basis in fact, but also because it looks like writings of a mad man....
POE(Power Over Ethernet) It refers to power transmission technology itself, and its components are divided into PSE and PD.It is a technology that can transmit power and data to devices over Ethernet using Cat 5 twisted-pair cables.It can operate without...
