STMicroelectronics Interview Questions and Answers

Nonblocking operations allow the program to continue executing other tasks while waiting for a response, while blocking operations halt the program until a response is received.

• Nonblocking operations allow for asynchronous communication, while blocking operations are synchronous.

• Nonblocking operations are typically used in event-driven programming, while blocking operations are common in traditional procedural programming.

• Example: Nonblocking I/O operations in networking allo...read more

DFF stores data based on clock signal, while latch stores data based on enable signal.

• DFF stands for Data Flip-Flop, while latch is a level-sensitive storage element.

• DFF stores data on the rising or falling edge of the clock signal, while latch stores data when the enable signal is high.

• DFF has two stable states (0 or 1), while latch has only one stable state.

• Example: D flip-flop, T flip-flop are examples of DFF, while SR latch, D latch are examples of latch.

Race condition is a situation in which the output of a program depends on the sequence or timing of uncontrollable events. Stuck at zero fault is a fault in digital circuits where a signal line is stuck at logic zero.

• Race condition occurs when multiple processes access and manipulate shared data concurrently without proper synchronization.

• Stuck at zero fault is a common fault in digital circuits where a signal line is constantly held at logic zero due to a manufacturing defec...read more

EM stands for electromagnetic interference, and it can be mitigated through shielding, grounding, filtering, and proper layout design.

• Shielding: Using materials like conductive foils or metal enclosures to block EM waves.

• Grounding: Connecting electronic components to a common ground to reduce interference.

• Filtering: Using capacitors and inductors to filter out unwanted frequencies.

• Proper layout design: Keeping sensitive components away from sources of EM interference.
