Study Notes
Design Methodology
- Design levels include gate level, register level, and processor level design.
- Sequential and combinational circuits are a part of gate and register level design.
Processor Design
- Processor organization, instruction representation, and instruction sets are included.
- Instruction formats (types and implementation), CISC, and RISC vector concepts are part of the study.
Arithmetic Operations
- Fixed point and floating-point arithmetic are covered.
- Algorithms for addition, subtraction, multiplication, and division are addressed.
Control Unit
- Hardwired and microprogrammed control units are detailed.
- Their organization, types, and operations are specified.
Memory Organization
- Memory hierarchy, allocation, segmentation, paging, and high-speed memory types are covered
- Virtual memory is a hierarchical storage system, managed by the OS
- Cache memory speeds up access by storing frequently used data closer to the CPU.
- Main memory stores data that the CPU may need frequently but access is slower than cache.
8085 Microprocessor
- 8085 microprocessor features, architecture, and instruction set are explored.
- Details about EU and BIU activities, segmentation, and address transactions are given.
System Modeling
- System modeling involves drawing graphs.
- Nodes (vertices) and edges (lines) are shown to visualize the system components and connections
System Modeling Concepts
- Structure and behavior are crucial concepts in system modeling.
- Operations, steps, and components, as well as relationships between them, are determined.
- Systems are divided into nodes and edges to show the connections between components.
Design Problem
- Tasks involved in designing a system are analyzed such that
- The designer needs to address how to achieve a desired behavior, using available resources efficiently, and making the system cost-effective.
- Given the specifications and components, the designer has to consider performance evaluation during design.
Data and Control
- Data processing and control units are the two parts of any complex digital system.
- The CPU is divided into dataproc. unit to perform operations on data and a control unit controlling the operation of the CPU
- The CPU's ALU is the data processing unit while CU is responsible for controlling memory, ALU.
Gate Level Design
- Types of gates (AND, OR, NOT, NAND, NOR, XOR, XNOR) are included.
- Their algebraic expressions, truth tables, and circuit diagrams are covered..
Combinational Circuits
- These circuits' outputs depend only on present inputs.
- Truth tables and logical equations are used to design these circuits.
Half Adder
- Logic diagram, truth table, and circuit diagram
- Used with two binary bits and produce Sum (S) and Carry (C).
Full Adder
- Logic diagram, truth table, and circuit diagram
- Used with three binary bits to handle carry-in, produce Sum (S) and Carry Out (C).
Sequential Circuits
- Sequential circuits' output depends on both present and past inputs.
- Memory is a crucial component, which differentiates them from combinational circuits.
Flip-Flops
- Fundamental digital memory elements
- Different flip-flop types (SR, JK, D, T) with their logic diagram, truth table.
- Key properties, operations, and characteristics of each are covered.
Counters
- Electronic devices for counting clock pulses
- Types include asynchronous (ripple) and synchronous counters.
- Design steps, circuit diagrams.
Register Level Design
- Data is processed as words.
- Components are word-oriented.
- Types are combinational and sequential.
- Storage of binary data using flip-flops.
Shift Registers
- Shift registers are used to store and shift data in a sequence.
- Types include SISO, SIPO, PISO, and PIPO, showing their data transfer properties
Multiplexer
- A device allowing 1 input from many.
- A multiplexer takes several input bits and selects one of them as the output based on selection inputs
- Shows the circuit diagram and describes operations with various example situations
De-multiplexer
- A device to send one input to any of many outputs
- The output chosen depends on selection inputs.
- Shows circuit diagram and describes operations with example situations.
Encoder
- Converts multiple inputs, typically binary codes, into a smaller number of output codes
- Shows truth table and circuit diagram for example situations
Decoder
- The opposite of an encoder. It converts a smaller input code into a larger output code.
- Shows truth table and circuit diagram for example situations
Processor Level Design
- Central Processing Unit (CPU) organization
- Instruction sets, buses, and memory interactions are part of this design level.
CPU
- Central Processing Unit (CPU) is in charge of the processing of data, following instructions.
- Data processing, control unit, and memory interactions are part of its operations.
- CPUs have buses to communicate among different units
- CPUs have different types of internal units to facilitate more complex operations.
Buses
- Buses are communication paths in the computer system.
- They allow components to send data among them.
- Three types of buses (controllers) are addressed (address, data, control), to facilitate data transfer between different units of computer systems
Queuing Model
- A model that explains a queuing system to solve the speed mismatch between CPU and main memory.
- Involving task arrival, service time, an average number of tasks to be executed in the queue.
- Two types of queuing models addressed (single queue, single server and multiple queue, multiple server).
Simulation
- A technique for modeling and analyzing complex systems.
- Simulators are used to model the behavior/operation of a device or system in a computer.
- Types of simulators (robotics, forecasing, traffic, and street lights). These simulators are used for design and testing purposes
Information Representation
- Binary representation of data in computers and its various types (fixed point, floating point, BCD, EBCDIC, ASCII)
- Computer data is encoded as a binary form. Various examples of coding systems (BCD, Binary coded decimal, EBCDIC, ASCII) are shown
Error Detecting and Correcting Codes
