Question 12

OpenSDA

Answer 12

r. OpenSDA is an interface between a PC and the target
MCU. Specifically, it is an in-system programmer/debugger that allows the user to transfer the
compiled application code from the IDE into the target MCU TO RUN THE APPLICATION

Question 13

Bootloader

Answer 13

– a small program that initially runs on a device and then, it launches the primary application
to run on the device

Question 14

Firmware

Answer 14

any read-only-memory resident program. Firmware such as the program of an embedded
system may be the only program that will run on the system and provide all of its functions.

Question 25

characteristics of an embedded system

Answer 25

Must respond to sequences and combinations of events * Real-time systems have deadlines on responses * Typically, must perform multiple separate activities concurrently * Fault handling – there is a lot of code to handle special cases, errors and faults * Diagnostics – help service personnel determine problem quickly

Question 26

What does a “real-time system” mean?

Answer 26

A real-time system reacts to things that happen in the world or events). hence when an event occurs, the system takes in a system input, process it, and outputs the appropriate output. if there is a strict timeline for response it is a hard one
