The instruction decoder is used to decode the instruction from machine code (1 byte). It is a combinational logic block with a one-hot encoded output as the processor can only carry out one instruction at a time. The instruction decoder was built in Verilog using case statements derived from the control signals. Se mer The aim of this project is to design a simple CPU and implement the design in Verilog. The CPU presented (from http://www.simplecpudesign.com/simple_cpu_v1/index.html) in this project is capable of adding and subtracting 8 bit … Se mer This CPU has five main components: multiplexers, an arithmetic logic unit (ALU), a decoder, registers, and memory (RAM) as seen here: The CPU is comprised of 3 multiplexers, 3 registers, a decoder and the ALU. … Se mer After verifying the functionality of each of the individual modules, the entire system was assembled following the architecture in the following figure. … Se mer The modules were tested individually during their development. This made it easier to find bugs in the designs and is in keeping with the hierarchical design and verification mindset … Se mer Nettet16. des. 2024 · )ther alternative: Emacs has verilog-mode which has a AUTO_LISP and AUTO_PERL expansion templates.
