UDP is preferred over TCP in this project due to its low latency and lightweight nature.

• UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

• UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

• UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...read more

To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

• Create a mask with the 7th bit set to 0 and all other bits set to 1

• Perform a bitwise AND operation between the register and the mask

• Store the result back in the register

Design logical circuits for arithmetic circuits in a blackbox.

• Understand the functionality of the arithmetic circuits in the blackbox.

• Identify the inputs and outputs of the blackbox.

• Design logical circuits using logic gates to replicate the arithmetic operations.

• Test the logical circuits to ensure they produce the same outputs as the arithmetic circuits.

Recursion in embedded C-code allows a function to call itself, useful for repetitive tasks or complex algorithms.

• Ensure proper base case to avoid infinite recursion

• Use stack space efficiently as embedded systems have limited resources

• Avoid recursive functions with deep call stacks to prevent stack overflow

• Example: Recursive function to calculate factorial of a number

Semaphore is a synchronization tool used to control access to a shared resource.

• Semaphore maintains a count of available resources.

• A process can request access to a resource by decrementing the semaphore count.

• If the count is zero, the process is blocked until a resource becomes available.

• When a process is done with a resource, it increments the semaphore count.

• If there are blocked processes waiting for a resource, one
