,1. Question:
In microprocessor‑based real‑time control systems, which
scheduling method best guarantees deterministic execution of
high‑priority tasks?
a. Round‑robin scheduling
b. Cooperative multitasking
c. Priority‑based preemptive scheduling
d. Batch processing
ANS:
c. Priority‑based preemptive scheduling
Rationale:
Priority‑based preemptive scheduling ensures that high‑priority
tasks can preempt lower‑priority ones, a necessity for meeting hard
real‑time deadlines in control systems.
2. Question:
Advanced media processing applications that require high data
throughput often rely on which microprocessor feature to minimize
CPU intervention during data transfers?
a. Interrupt‑driven I/O
b. Direct Memory Access (DMA)
c. Polling routines
d. Caching mechanisms
ANS:
b. Direct Memory Access (DMA)
Rationale:
DMA channels allow peripherals to transfer data directly to or
from memory without constant CPU intervention, boosting overall
system throughput.
3. Question:
Which microprocessor architecture is renowned for its low power
consumption and is frequently employed in battery‑operated

, embedded systems?
a. x86
b. ARM Cortex‑M series
c. PowerPC
d. MIPS
ANS:
b. ARM Cortex‑M series
Rationale:
The ARM Cortex‑M series is optimized for low‑power, low‑cost
applications, making it ideal for embedded systems and portable
devices.
4. Question:
In automotive microprocessor applications, which characteristic is
most critical to ensure safety‑critical operation?
a. Extreme clock speeds
b. Fault‑tolerant and robust design
c. Extensive multimedia capabilities
d. High‑resolution graphics
ANS:
b. Fault‑tolerant and robust design
Rationale:
Automotive systems demand reliability and the ability to sustain
failures gracefully; fault‑tolerant designs and robust error correction
are thus paramount.
5. Question:
In real‑time audio processing applications, which set of
peripherals is most crucial for digitizing and reconstructing analog
signals?
a. Timer and counter circuits
b. Analog-to‑Digital Converters (ADC) and Digital-to‑Analog
Converters (DAC)
