ram rom selector

These are example circuits targeted to 8-bits homebrew computers. They are simple circuits to select between ROM and RAM memories when they share partial block of address space, i.e. if you have a big ROM chip, let's say 32K but you won't use it every single cell of it. So you can set a ROM and a RAM chip on the same address space and set your computer to select the proper one.
Let me explain. Let's say that you have 1x 32K ROM chip and 2x 32K RAM chips and you're using a Z80. The Z80 needs ROM on the first page of the address space because at reset it points to $0000 address cell. But your firmware only occupies 16/18 KB of space. So you can build this RAM/ROM selector using simple chips from the 74xx series and let the computer switches between the 2 kinds of memory. In the first one, for example, the CPU reads from ROM chip up to address $4FFF (20,479), then reads/writes from/RAM. In the second one, the CPU addresses the ROM for the first 24K of memory then switches to RAM

This is a CPU witch is capable of executing a lot of stuff in one clock cycle, and this CPU can shift left up to 7 times and shift right up to 7 times witch means that it is possible to  multiply and divide in one clock cycle if you program a table in the program memory. it has a 32 bit instruction width and a 8 bit address. it also has 

The ALU has the following operations:

  • ADD
  • SUBTRACT
  • SHIFT_LEFT (up to 7 times per cycle 3 bit)
  • SHIFT_RIGHT (up to 7 times per cycle 3 bit)
  • XOR
  • OR
  • NOT

AND and NOT

I used CircuitVerse as an alternative to the paid circuit simulator apps. One thing I love about making circuits is starting from nothing. I limited myself to using only two gates: AND and NOT. I copied this idea from the game made by Sebastian Lague. This project starts from using the built-in AND and NOT gates.
