asciilifeform: there are not so many original things in the field.
asciilifeform: tput bit. The design engineer was supposed to make that signal do something useful, like load the PC with some address.'
asciilifeform: 'So the inevitable question is "how did a jump work?" That was entirely up to the engineer crafting the circuits. The OEN instruction could be used to disable any changes occurring on the output data; at the end of a loop assert OEN and let the machine execute whatever instructions - hopefully NOPs - remained until the PC rolled over. There was a JMP, but that instruction simply toggled an ou
asciilifeform: 'it didn't have a program counter. Designers were expected to create one external to the CPU. It's width was, well, anything the developer wanted. Running a tiny bit of code? Maybe an 8 bit PC was appropriate. Or 32 bits for those applications needing 4 GN (giga-nibbles) of powerhouse processing.'
asciilifeform: he more pessimistic related-key model, one can show that any 16-round differential path for any of the LED versions will contain at least 50 active Sboxes.'
asciilifeform: 'The LED lightweight block cipher provide strong security arguments against all state-of-the-art attacks, even in the related-key model. In particular against differential and linear cryptanalysis: one can easily show that any 4-round differential path for any of the LED versions will contain at least 25 active Sboxes (i.e. Sboxes with a non-zero difference) in the single-key model. Even in t
