• Setup time is the minimum amount of time data must be stable before the clock edge for proper capture.

• Hold time is the minimum amount of time data must be stable after the clock edge for proper capture.

• Violating setup time can lead to metastability issues.

• Violating hold time can lead to data corruption.

• Example: If setup time is 5ns and hold time is 2ns, data must be st...read more

Flexibility on work timings is important for work-life balance and productivity.

• Flexibility in work timings allows employees to better manage personal responsibilities.

• It can lead to increased employee satisfaction and morale.

• Remote work options can provide flexibility in work timings.

Iterative fibonacci function using a loop to calculate the Fibonacci sequence.

• Initialize an array to store Fibonacci numbers

• Use a loop to calculate each Fibonacci number based on the previous two numbers

• Return the array of Fibonacci numbers

Reverse a linked list

• Iterate through the linked list and reverse the pointers

• Use three pointers to keep track of current, previous, and next nodes

• Update the next pointer of each node to point to the previous node

FIFO full condition occurs when the FIFO buffer is completely filled with data.

• Occurs when the number of items in the FIFO buffer reaches its maximum capacity

• Further writes to the FIFO buffer are blocked until some data is read out

• Can lead to data loss if not managed properly

Operating refers to the process of running a computer system or software.
