Introduction to Embedded System Design Quiz

Study Notes

Improving Processor Performance

One way to improve processor performance is to increase the number of processing cores, as multi-cores enable multiple threads to be executed simultaneously, increasing overall processing power.

Power Consumption

Increasing logic density and clock speed can significantly increase power consumption, which is a critical concern in modern computing.

Specialized Co-processors and Processing Units

Specialized co-processors and processing units are important in processors as they enable efficient processing of specific tasks, such as graphics, audio, and encryption.

Embedded Systems

The main characteristic of an embedded system is that it is designed to perform a specific task or set of tasks.
An embedded system can be described as a combination of computer hardware and software designed to perform a specific function or set of functions.
In an embedded system, software is typically stored in ROM (Read-Only Memory) or Flash memory.
Examples of embedded systems include microwave ovens, traffic lights, and medical devices.
The five characteristics of an embedded system are:
- Real-time operation
- Limited resources
- Interrupt-driven
- Low power consumption
- High reliability
The microprocessor is considered the heart of any embedded system.
The primary factor that determines the performance speed of a processor in an embedded system is clock speed.
Digital signal processors (DSPs) are commonly used for voice and image processing in devices like mobile phones and digital cameras.
