A 0.6 Hz full-fledged WiFi-less 29-bit computer based on photon technology. Rather fast. WARNING: May lag. Note: The first part of the default program does not require input. Press the On button and LightPC will print Pascal's Triangle automatically.

    What is an MMU? By 24 bit do you mean up to a 24 bit number or 24 different instructions? What do you mean you can only fit 64 different ones? What do you define as a "CPU core". Sorry for all the questions I don't have much experience non-TPT computer hardware.

    My plans are to have a coprocessor that manages program load requests for each core. So when one core is running, another core can ask the MMU to load a program or the next part of the program from memory and invoke an automated process.

    Ah, so repeatedly using certain console commands to send a bunch of PSTN to one location? Also, let's say if I had multiple mini CPU cores for a TPT computer, what would be a good size in terms of instructions for each core's L1 instruction cache? The design I'm working on will be able to fit 64 24 bit instructions. Should I ramp it up to 128?

    Well you can do that (sort of) right now using layering, I myself have used it extensively (and when the update comes out I will have to fix all my saves for it).

    I just read online on the powder wiki what unofficially seemed to be the plan that PSTN will eventually be able to have the amount it extends and retracts set based on the number of increments by 10 C from 0 C in temp. Hence PSTN with a temp of 160 theoretically could push 16 FILT particles in a dense memory array but using only one or two PSTN particles.

    @Schmolendevice: What is going to be in there that can make it more compact?

    Hehe, waiting for update 91 so I can make my FILT memory more compact.

    Sorry, with Boolean algebra * is an AND operation, I believe in C and Java, ^ is XOR and technically | (shift + backslash) was OR. I was referring to segments of the Boolean equations for the full adder logic circuit.

    @Schmolendevice Honestly I'm a little lost with your notation, specifically the asterisk in "I always need to pass on the first A * B and A ^ B to some DTEC so I can OR the A * B with the Carry In OR (A ^ B)." ARAY/FILT technology in fact allows addition to be done in constant time (so 0 frames per bit) by manipulating the algebra a little.

    Here's the ID for that one unless I have to publish it. I'm not fully familiar with 'private save sharing.' ID:1703470. Notes in scene.
