Problem $5.(18$ points$)$ True or False. Circle your choice.

a$.$ In some cases, embedded processors can ignore interrupts.

True

False

b$.$ Counters can be used as clock dividers, but only for power of two ratios $($e$.$g$.,$ from $256MHz$ to $16MHz,$ or from $128MHz$ to $32MHz).$

True

False

c$.$ Flash memory is volatile.

True

False

d$.$ Modern SoCs may have CPUs, GPUs, FPGAs, and ASICs on the same chip.

True

False

e$.$ Embedded real$-$time systems can have hard timing constraints, firm timing constraints, or soft timing constraints, but cannot have all of them.

True

False

f$.$ In static priority based preemptive scheduling, when task deadlines are lower or equal to their periods, deadline monotonic scheduling policy is optimal among all fixed$-$priority schemes.

True

False
