Digital Design

1

Digital design introduction.
Boolean algebra.
Logic gates and their symbols, combinational circuits, Boolean functions and their representations.

2

Number representations, representing binary numbers. Two's complement representation. Arithmetic operations.
Hardware design with CAD system, hardware description languages: Verilog, Verilog module. Assignment operation.

3

Basic combinational building blocks: decoder, encoder, multiplexer, demultiplexer, comparator, full adder.
Verilog: always block, registers. Describing the behavior of functional components.

4

Sequential circuits: bits storage. Clock signal, timing requirements.
Finite state machine (FSM): specification -> state diagram -> implementation.
Verilog: edge sensitive always block, describing FSMs.

5

Datapath components: multifunction register, shift register, counter.

6

Datapath components: register fly, RAM, ROM, FIFO, LIFO

7

Designing complex circuits high level state machines. Separation of the datapath and controller, hierarchical construction of digital circuits using datapath components. .

8

Programmable processors: controller and datapath, addressing.
The MiniRISC processor:  instruction execution.

9

The MiniRISC instruction set.  Addressing modes. Describing programs with flowchart diagram. Assembly programming.
Loops and subroutines.

10

Peripherals and their programming interface (mode, command, state and data registers). Bus: data, address, Connecting peripherals to the processor.

11

Peripherals: GPIO, timer.
Processor - peripheral communication. Interrupts.

12

Interrupt handling.

13

Interfaces for data transfer: UART, SPI.
