Beschreibung
MyNOR is a single board computer that does not have a CPU. Instead, the CPU consists of discrete logic gates from the 74HC series. This computer also has no ALU. Only a single NOR gate is used to perfom all computations such as addition, subtraction, AND, OR and XOR. This computer is not fast, it is rather slow. MyNOR can only perform 2600 8-bit additions per second, although it is clocked at 4 MHz. This is because everything is done in software. MyNOR has only a 32 kB ROM for program storage, but this is more than enough. The very slim microcode occupies only 9 kB, the remaining 23 kB are used for the application program.
