2. 0:12hello
3. 0:13and welcome back this is actually a
4. 0:15major milestone in this course
5. 0:17and in your education in computer
6. 0:20science in general
7. 0:21what we have done so far is quite
8. 0:24amazing
9. 0:25we came from the top from high-level
10. 0:29languages to assembly language machine
11. 0:31language
12. 0:32and figured out how to make that
13. 0:34high-level language compile to something
14. 0:36understandable by the machine then we
15. 0:38came from the bottom
16. 0:41and started with the gates boolean logic
17. 0:44and
18. 0:44build a fully working computer
19. 0:48we made a contact the
20. 0:51hardware met the software it's quite
21. 0:54amazing
22. 0:55if you just realized how far we got it's
23. 0:58okay you can start screaming you can
24. 0:59yell downstairs
25. 1:01too your parents if you're at home hey
26. 1:03mom
27. 1:04we made contact if they don't understand
28. 1:06what they're saying doesn't matter
29. 1:08it's okay you can explain to them that
30. 1:10you finally realize what you've been
31. 1:12doing
32. 1:12if you are away from the home
33. 1:16call them tell them hey i've made the
34. 1:18contact tell that to your younger
35. 1:20siblings or older siblings
36. 1:24this is a part actually this is time to
37. 1:26celebrate
38. 1:27we're gonna have in a live session a
39. 1:29little bit of a celebration
40. 1:32anyway um to recap
41. 1:35we have really built a working processor
42. 1:37it can execute any of the risk 5
43. 1:39instructions and therefore we can
44. 1:41compile a c program to it
45. 1:44we have seen that
46. 1:48it is not probably the best and most
47. 1:51performant processor that can be built
48. 1:55is it has a fairly long critical path
49. 1:58but that's okay
50. 1:59that will keep us busy for the rest of
51. 2:01the semester and what we'll see
52. 2:03everything is going to be logical from
53. 2:05now on
54. 2:06and hopefully things are just going to
55. 2:09be smoother
56. 2:10all what we are doing from now till the
57. 2:13end of the semester
58. 2:15we are generally improving this design
59. 2:19and adding some more features and
60. 2:22learning
61. 2:22the world that surrounds it so we have
62. 2:25built our data path
63. 2:27we understand our phases of execution
64. 2:29and we have designed the controller
65. 2:32and that's it for now see you in the
66. 2:34next module when we make
67. 2:35a better processor
