My CPU

The picture below depicts the overall architecture of the FunCPU. It employs a 8 bit wide databus and a 9 bit wide address bus. Please recall, that although the databus is 8 bits wide, due to the nature of the tagged architecture only 7 out of 8 bits can be used externally (i.e. by the program), and…

The ALU module is very simple and straightforward. It is mounted together with the control board encoding logic on a single board. It performs a simple addition operation on the two operands as described in the following table. The two selector bits define the two input sources. ALU…
