| - | ====== EuroTwo CPU ====== | + | |
| - | The EuroTwo CPU is the little sister of the [[projekte: | + | |
| - | I planned to implement | + | |
| - | * A simple instruction set | + | |
| - | * Three 4-Bit registers | + | |
| - | * One 8-Bit programcounter register (PC) | + | |
| - | * One 12-Bit instruction register (IR) | + | |
| - | * A simple ALU | + | |
| - | * 4-Bit Databus | + | |
| - | * 4-Bit Addressbus | + | |
| - | * 8-Bit Addresssbus for ROM | + | |
| - | * 8-Bit Instructionbus | + | |
| - | * 16 words (4-Bits) of RAM for data-memory | + | |
| - | * 255 triple-words (12-Bits) of ROM for program-memory | + | |
| - | * Thus it is a havard architecture! | + | |
| - | * Thus it might have a maximum of 255 machinecode instruction | + | |
| - | * No microcoding is implemented | + | |
