What is the main difference between Harvard architecture and Princeton architecture?

Harvard architecture uses separate buses to access code and data simultaneously, while Princeton architecture uses a single bus for both code and data.

In Harvard architecture, one memory contains only the program code and the other memory contains only the data, while in Princeton architecture, both program code and data share the same memory. (correct)

In Harvard architecture, program code and data share the same memory, while in Princeton architecture, separate memories are used for program code and data.

Harvard architecture uses a single clock cycle to access both program code and data, while Princeton architecture requires separate clock cycles for program code and data.

Why is a single clock cycle sufficient in Harvard architecture?

Because it uses a more efficient memory management system than Princeton architecture.

Because it eliminates the need to switch between program code and data in the same memory.

Because it has a faster clock speed compared to Princeton architecture.

Because it uses separate buses to access code and data simultaneously. (correct)

What components are typically integrated within a microcontroller unit (MCU)?

Program Counter, Instruction Register, Arithmetic Logic Unit (ALU), Control Unit

Central Processing Unit (CPU), Random Access Memory (RAM), Read-Only Memory (ROM), Input/Output (I/O) ports

FPGAs offer high performance, low power consumption, and can be optimized for specific tasks. They provide flexibility in design and can be re-programmed after production, unlike ASICs which have a fixed configuration after production. 13 Common hardware architectures used in embedded systems:  System in Package (SiP):  SiP refers to the integration of multiple chips and components into a single package.
