This week, I will talk about my feelings and opinions on "Microprocessors and Computer system" first.
This course is based on the study of a widely used microprocessor--Intel 8086.It's appearance is as below:
(The pin graph of 8086 )
And we learned the basic functions of each pin and how it works to implement some basic operation,such as reading and writing.I'm surprised to find that every seemingly simple action actually needs many steps to implement,and only when every part of the processor cooperates well can it accomplished the operation.
Knowing how the computer works step by step is interesting an amazing.
(The basic steps of how processors work)
I used to think I'm familiar with the computer since I use it every day.But now I know that it's not that simple.Many efforts have been made by thousands of engineers and scientists and many complex methods have been used to design a computer to provide us, the users a really simple and friendly using experience.Many times,the more seemingly simple product actually is the result of more efforts.
So, I begin to know that the essential work done by engineer is not only about those complicated math and physics, but more about how to encapsulate those difficult things into easy and friendly products or designs.
This course even reminds me of the slogan of Philips,that is "Complicated the mind,simple the action".Now,I have a deeper understanding about it after taking this course.I've made up my mind that I would try to learn more not only about the principles and basic theories about engineering,although they are of great importance,I would also try to obtain more understanding and experiences about how to design and improve the function of products in real life.
