MICROPROCESSOR

Identify the type of architecture that uses a single bus for both instructions and data.

• Harvard Architecture

• Von Neumann Architecture

• Parallel Architecture

• RISC Architecture

__________ are the features of Harvard Architecture that results in faster execution compared to Von Neumann Architecture.

• Separate buses are used for data and instructions, allowing parallel access

• Data and instructions are processed sequentially

• A single bus is shared for data and instructions

• A unified memory block reduces hardware requirements

Compare the control bus structure in Von Neumann and Harvard architectures and identify the primary difference.

• Von Neumann uses separate control buses for data and instructions, unlike Harvard

• Von Neumann eliminates the need for a control bus entirely

• Harvard uses separate buses for data and instructions, unlike Von Neumann

• Harvard supports sequential operations using a single control bus

Assess the drawback of using Von Neumann Architecture in a real time embedded system.

• Single bus structure limits simultaneous operations

• Simpler hardware design increases cost.

• Pipelining is mandatory, which slows execution

• Separate memory for data and instructions complicates the design

Identify the key advantage of Von Neumann Architecture over Harvard Architecture.

• It enables faster data access

• It simplifies hardware design for lower-cost systems

• It supports parallel processing inherently

• It allows more efficient pipelining

_________ is the component that combines memory, CPU, peripherals, and I/O interfaces into a single chip

• Microcontroller

• Microprocessor

• Harvard Architecture

• Von Neumann Architecture

Assess the advantages of incorporating memory, a CPU, and I/O interfaces into a single chip in microcontrollers.

• Increases complexity but improves speed

• Eliminates the need for external peripherals

• Reduces cost and size while enhancing functionality

• Focuses only on improving input/output performance
