16 Questions
What is the main difference between Harvard architecture and Princeton architecture?
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.
Why is a single clock cycle sufficient in Harvard architecture?
Because it uses separate buses to access code and data simultaneously.
What components are typically integrated within a microcontroller unit (MCU)?
Processor, RAM, flash memory, serial receivers and transmitters
How does Harvard architecture handle memory access for program code and data?
It uses separate buses for program code and data to access them simultaneously.
What is the primary purpose of a microcontroller unit (MCU) in an embedded system?
To control specific functions within a larger system or device
Why does Harvard architecture use separate program and data memories?
To allow for simultaneous access to program code and data.
In which type of memory does Harvard architecture store only the program code?
Flash Memory
FPGAs are well-suited for applications that require real-time signal processing and data manipulation, making them well-suited for applications that require real-time signal processing. Common hardware architectures used in embedded systems: Application-Specific Integrated Circuits (ASICs): ASICs are custom-designed chips that are specifically tailored for a particular application.
Field Programmable Gate Arrays (FPGAs)
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.
Field Programmable Gate Arrays (FPGAs)
The choice of hardware architecture depends on factors such as the application requirements, performance needs, power constraints, cost considerations, and development resources available. Designers evaluate these factors to select the most appropriate hardware architecture that meets the specific needs of the embedded system. 15 The ARM Cortex-M0+..
