CS 352 Lecture 17 – Catchup
Dear students,
Last week lots of good misunderstandings of memory came up. When misunderstandings appear, the right things are happening. Conflict surfaces in your brain, which is step 1 of learning. Step 2 is resolving that conflict. Today, then, I want to start by revisiting some ideas of how memory and pointers work in C and really in the entire computer.
I will unveil the following programming one line at a time. Your job is to determine what’s happening.
0: ... 1: ... 2: ... 3: ... 4: ... 5: ... 6: ... 7: ... 8: ... 9: ... 10: ... 11: ... 12: ... 13: ... 14: ...
Some folks have expressed confusion about HDL and n-way components. Also, the next homework requires doing some HDL tricks that I don’t think are necessarily intuitive. Rather than continuing to build on a wobbly foundation, let’s sketch out schematics for some of these components and translate them to HDL. We’ll visit these: Mux4Way, DMux4Way, Inc16, LeastByte (which is not part of any homework), ALU, Bit, Register, RAM8, RAM64, and PC.
See you next class!
