Adders and Subtractors
- Half-Adder and Full Adder
- Ripple carry adder
- Carry look ahead adder
ALU - Arithmetic Logic Unit
- Multipliers - Combinatorial and Sequential
- Division - Combinatorial and Seqiential
Memory
- ROM
- Static / Dynamic RAM
- Synchronous / Asynchronous RAM
- LUT based RAM vs. Flip-Flop Based Registers
- Block RAM
- Dual port / Single port RAM
Where would you use FPGA memory ??? - (Topics which will be covered in lessons xx)
- FIFO buffers - read more here
- Waveform generators (sinus for instance) - read more here
- Program memory for the PicoBlaze - read more here

	Examples and Problems:
	ROM based BCD to 7-Segment conversion Multiplexed Display (Work-through of the solutions) SPI - Serial Peripheral Interface: The purpose of these pages to introduce the problems you will have to face creating a SPI Create an 8-bit version of the 74x382 ALU Make a simple RPN calculator

	Resume:
	One of the original purposes for logic-devices was the creation of the Computer which could perform arithmetic operations automatically. The Full-Adder an important component in all the basic arithmetic operations: + - * and /. When it comes to implementing arithmetic in a FPGA
