This set of Embedded Systems Multiple Choice Questions & Answers (MCQs) focuses on “Debugging Technique:Xray”.
1. Which of the following has a single set of compiler and the debugger tools?
a) Xray
b) onboard debugger
c) emulation
d) high-level simulator
View Answer
Explanation: The Xray debugging technique is a product from the Microtec which is having a complete set of compiler and debugger tools which will work with the simulator, debugger, emulator and the onboard debugger.
2. Who developed the Xray product?
a) IBM
b) Intel
c) Microtec
d) Motorola
View Answer
Explanation: The Xray which is a product from the Microtec is having a complete set of compiler and debugger tools.
3. Which part of the Xray can interface with a simulator?
a) emulator
b) debugger
c) simulator
d) onboard debugger
View Answer
Explanation: The Xray consists of the consistent debugger which can interface the emulator, simulator, task level debugger or onboard debugger.
4. Which can provide the consistent interface to the Xray?
a) emulator
b) simulator
c) memory simulator
d) debugger system
View Answer
Explanation: The Xray consists of the debugger which interfaces with the emulator, simulator, onboard debugger that provides the consistent interface to the Xray product. This can improve the overall productivity of the product since it does not require any relearning.
5. Which of the following can access the information directly in the Xray?
a) emulator
b) debugger
c) simulator
d) hardware
View Answer
Explanation: The Xray obtain its debugging information from a variety of sources and how it access these sources. The simulator can access direct information but the emulator can access the information via a serial line or via the ethernet or directly across a shared memory interface.
6. Which of the following access the information through the ethernet in a Xray?
a) simulator
b) debugger
c) onboard debugger
d) emulator
View Answer
Explanation: The Xray obtain its debugging information from a variety of sources. The emulator can access the information via a serial line or via the ethernet or directly across a shared memory interface and the simulator can access the direct information.
7. Which tools help the Xray allows the software to be developed on the host system?
a) compiler tool
b) simulator tool
c) debugger tool
d) emulator tool
View Answer
Explanation: The compiler tools allow the software to be developed on the host system and this system does not have to use the same processor as the target.
8. Which of the following is ideal for debugging codes at an early stage?
a) compiler
b) debugger
c) simulator
d) emulator
View Answer
Explanation: There are a variety of ways for executing the codes. The simulator provides an ideal way for debugging the codes at an early stage, that is before the hardware is available and it can allow the software to proceed in parallel with the hardware.
9. How can we extend the power of Xray?
a) Xray interface
b) Xray memory
c) Xray input
d) Xray peripheral
View Answer
Explanation: The power of the Xray product can be extended by the Xray interface method from the operating system debugger.
10. Which of the following uses the Xray interface method to provide the debugging interface?
a) pSOS+m
b) pSOS
c) pSOS+
d) NAP
View Answer
Explanation: The pSOS+ uses the Xray interface method to provide the debugging interfaces which can extend the power of the Xray.
11. How is the processor enter into a BDM state?
a) BDM signal
b) Start signal
c) BDM acknowledge signal
d) Start signal of the processor
View Answer
Explanation: The assertion of the BDM signal or by executing the special BDM instruction, the processor enter into the BDM state and when the processor enters into the BDM mode, low-level microcode takes the processor which allows the breakpoint to be set, registers to be accessed and so on.
