Concepts from Chapters 5-7 (Midterm II)

Chapter 5 - Arithmetic

- number bases (bin, oct, dec, hex) and conversions between them
- signed numbers (sign-magnitude, 1's complement, 2's complement)
- Addition - ripple carry and carry look ahead
- Signed and unsigned addition/subtraction (carryout and overflow)
- number representation in Verilog
- unsigned multiplication
- BCD addition
- ASCII codes

Chapter 6 - Combinational Circuits

- muxes (data multiplexing and using them for logic)
- Shannon's expansion
- Decoders (data addressing and using them for logic) 
- Encoders
- Code converters (i.e. 7-segment display code converters)
- Verilog for combinational circuits (assign, always, if/else, case,
  for, etc.) 

Chapter 7 - Latches and Flip Flops

- basic D-latch (level-sensitive latch, or gated latch)
- SR-latch, gated SR latch 
- gated D-latch
- Master-slave and edge trigered flip flops
- clear and preset signals in flip flops
- T and JK flip flops
- Use of flip flops to build shift registers
- simple counter circuits
- Verilog for sequential circuits (always @ (posedge...), etc.)  
- blocking and non-blocking assignments in sequential Verilog
