Experimental observations show this FIFO is often becomes full, and usually having more than five elements. What does it mean? Choose A-F.
Consider the situation in which a FIFO queue is used to buffer data between a main program (e.g., SCI_InChar that calls RxFifo_Get) and an input interrupt service routine (e.g., SCIhandler that reads SCI0DRL and calls RxFifo_Put). Experimental observations show this FIFO is often becomes full, and usually having more than five elements. What does it mean? Choose A-F.
a) The system is I/O bound
b) Bandwidth could be decreased by increasing FIFO size
c) The system is CPU bound
d) The FIFO could be replaced by a global variable
e) The latency is small and bounded
f) Interrupts are not needed in this system
