Question 1

Embedded Systems

Answer 1

• combination of hardware and software which is designed to carry out a specific set of functions
• is electronic, electrical or electro-mechanical

Categories:

• microcontrollers
• microprocessor
• system on chips(SoC)

Question 2

Microcontrollers

Answer 2

CPU in addition to some RAM and ROM and other peripherals all embedded onto one single chip

Question 3

Microprocessor

Answer 3

integrated circuit which only has a CPU on the chip

Question 4

System of chips(SoC)

Answer 4

may contain a microcontroller as one of its components

they almost always will include CPU, Memory, input/output [1/0] ports, and secondary storage on a single microchip

Question 5

The programmability of Embedded systems

Answer 5

Non-programmable devices need, in general, to be replaced if they require a software upgrade

programmable devices permit upgrading by two methods
1. connecting the device to a computer and allowing the download (not finished)

Question 6

Benefits and Drawbacks of embedded systems

Answer 6

(memorize the table on google classroom)

Question 7

Embedded systems - Example

Answer 7

Motor vehicles
-modern cars have many parts that rely on embedded systems to function correctly. The diagram below shows some of the many components that are controlled in this way.
