243/Computer Architecture/Learning Resources

Interesting and helpful learning resources (short videos, demostrations, animations, magic tricks and etc. )

Some of the learning resources are shown in lectures, which are mainly used to encourage the students' interests and help to understand the related lectures' content. This has no relationship with the examination. So, feel relaxed to take the trip of computer Architecture! It would be much appreciated if you can let me know any suggestions or problems.

Lecture 1

  • Ones and Zeros
  • From text to binary and back again
  • Binary ASCII code Crop Circle

  • Why study assembly language
  • Easy 6250: first program
  • 6502 Instructions
  • Assembler
  • 3 addressing modes animation
  • Some programs to illustrate addrssing modes
  • Lecture 9

    This lecture is a bit advanced level. I am thinking of the examination questions no to be so complicated. Some of the students are confused about assembly language codes with regards to the examination. After some discussion, we think that the requirement for examination related the assembly language will be focused on developing the ability of "reading the codes" instead of "writing the code". So, you need to understand the assembly language. With regards to the codes, the final exam will not possible to require you to write codes, but will possibly require you to read codes. We hope this will release your confusion in studying this part and give you some guidance in preparing your exam. Please feel free to let me know if any problems.
