Study Notes

Computer Architecture vs. Computer Organization

Computer Architecture defines the functional behavior and high-level design requirements of a computer system.
Computer Organization details how a system's architecture is implemented at a low level, including hardware structure and relationships.
Major distinctions include:
- Architecture is concerned with "what" a computer does, while Organization focuses on "how" it performs those tasks.
- Architecture includes components like instruction sets and registers; Organization involves physical design aspects like circuits and peripherals.
Architecture is also referred to as Instruction Set Architecture (ISA), while Organization can be synonymous with microarchitecture.

Architectural Categories

Common architectural models include:
- Von-Neumann Architecture
- Harvard Architecture
- Micro-architecture
- System Design

Key Issues in Computer Design

Assumption of Infinite Speed and Memory: These unrealistic assumptions can lead to flawed design methodologies.
Speed Mismatch: Variances in processing speed between memory and processors can disrupt system performance.
Bug and Error Handling: Designers must devise effective strategies for identifying and resolving system errors to prevent failures.
Multiple Processors and Threads: Management of multi-processor and multi-threaded environments adds complexity to design.
Shared Memory Management: Requires careful handling to avoid process collisions.
Disk Access Management: Ensuring efficient access to multiple disks is a critical consideration.
Performance Optimization: Balancing processing power, memory, and input/output speed to maximize efficiency.
Power Consumption: Increasing focus on energy-efficient designs to mitigate environmental impact.
Security: Importance of embedding strong encryption and authentication in designs to protect sensitive data.
Compatibility Issues: Necessity for systems to work seamlessly across varying platforms and devices.

Essential Register Functions

Memory Address Register (MAR): Stores addresses of memory units.
Memory Buffer Register (MBR): Holds instructions and data being transferred to/from memory.
Program Counter (PC): Indicates the next instruction for execution.
Instruction Register (IR): Holds the current instruction to be executed.

Register Transfer Language (RTL)

RTL is symbolic for describing transfer operations between registers, closely resembling assembly language.
Micro-operations are small operations on data in registers, encompassing:
- Arithmetic Micro-operations: Include addition, subtraction, incrementing, and decrementing data in registers.
- Logic Micro-operations: Perform bitwise operations like AND, OR, and XOR.
- Shift Micro-operations: Involve moving bits left or right within a register, including logical, circular, and arithmetic shifts.

Types of Micro-operations

Register Transfers: Move binary data between registers.
Arithmetic Operations: Perform calculations using numerical data in registers.
Logic Operations: Execute operations on bits treated as binary variables.
Shift Operations: Adjust data position within registers, applicable for manipulation in calculations or data transfer.

Conclusion

Understanding the distinction between architecture and organization, along with the issues faced in computer design, is essential for effective system development.
Register Transfer Language provides a means to articulate and implement fundamental operations conducted at the register level.
