But how to design a CPU must start with a Spec., namely; Why design a CPU and make measurable benchmarks to achieve such as; - Macro instructions per second (MIPS) (more important than CPU clock),for example; - Intel's Itanium chip is based on what they call an Explicitly Parallel Instruction Computing (EPIC) design. - Transmeta patented CPU ...

Design a CPU from scratch in VHDL or Verilog. Design another CPU from scratch. Look at the ARM instruction set and design a compatible CPU. Make your ARM-Compatible CPU work in an FPGA. Don't distribute your VHDL/Verilog source code unless you want to be sued. Use your ARM experience to write a good dissertation for your PhD.

2016年11月22日 · Through reading Code, I understand the basic logic behind a CPU, and have begun building one in LogiSim. Chapter 17 in Code details the CPU I want to build, but the circuits lack key components -- clock signals, and instruction decoding. Some of the clock signals seem to be pretty obvious (the PC seems to need a steady clock signal) but others ...

2013年6月18日 · When you synthesize a design the synthesizer should give you a report on the resources used, like number of gates and RAM. This should give you an idea what parts are suitable for your design. Make sure you have enough headroom. Pick a part which has some extra RAM, which you'll need to execute programs on your CPU. edit (re your comment)

2017年4月6日 · One advantage of a single-cycle CPU over a pipelined CPU is predictability. This is important if you're using the processor for timing-critical operations, such as low-level "bit-banging" or real-time processing. An example is the Sitara processor used by the Beaglebone.

2016年5月25日 · \$\begingroup\$ @LeonHeller I usually agree with the questions you want closed, but CPU design is very much an electrical engineering question. This question could use some help to make it much more clear of what is wanted (like what konsalik is asking about) but that doesn't make it off-topic. \$\endgroup\$

Now you have the potential for naming confusion. Saying you have two CPU's could mean you have the older style two silicon packages or the newer single silicon package but with the processing setup of two processors. To resolve this we now mean CPU to be a single silicon package and a Core is a single logical processing unit within it.

2021年7月13日 · This philosophy of design and re-use, enabled by Mead and Conway's structured design and the standard cell libraries to support it, is what kicked chip design into high gear in the 1980s. Mead and Conway’s book Introduction to VLSI Systems is still available, and although it focuses on NMOS it is still relevant today.

2014年11月22日 · The "Microprocessor Design: Design steps" goes into much more detail. p.s.: Please help improve the current rough draft of the "Microprocessor Design" book to make it easier for the next person to design a processor. typical 8-bit CPUs... using 8-bit instructions ...

2017年4月24日 · Reset and clocking are actually part of the state machine learning, getting the state machine going and thinking in terms of each pass through the logic/code is a clock cycle in the cpu and you state variables are used on each pass to indicate what to do during that clock cycle, what is the current state, and based on the current state and ...
