I may have missed something in my quick read, but isn't this a 0 bit processor?
There is only one instruction, and no No-op,
To be a one bit, shouldn't there be 2 instructions? one for 0 and one for 1.
Again I apologize if I missed something, I get a little fuzzy about what a Single operation processor should be since 1 bit has 2 states.
- dfox 12y agoOne bit refers to it having exactly one bit of what could be called "architecture state" or "datapath", that is the second channel of lower 74C374 going from input to A0 of program store. "Instruction" has two phases and result of first phase determines what will happen next by means of this one bit (by changing which pointer to next instruction will be read from memory).
- rdc12 12y agoThat all makes it a one instruction set CPU (and since there is only one possible instruction it need not be stored in the program). But the 1 bit is a reference to memory, it has an address space os 2^1 (Q1 and Q2 on the 4099 output register file) and a word size of 1, which as you point out allows you to store only a binary state.
