Problem $1(6$ marks$)$: The interrupt vector table can be relocated. Write an

assembly language function conforming to the ARM Architecture Procedure Call

Standard $($AAPCS$)$ named "NVIC$\_$VTableRelocate" that relocates the NVIC Vector

Table within SRAM. One $32-$bit address must be accepted as a function argument

containing an SRAM address. The function will return true if the table

relocation was successful, or false indicating the table could not be

relocated.

The function must be complete $-$ the only requirement of a programmer to

call this function is the function argument. You must ensure that the SRAM

address conforms to the requirements of the NVIC $($verify alignment$/$boundary

of the argument before relocating the table$)$ and does not overlap the stack.

You may assume the stack occupies the range $0$x$20007800-0$x$20007$FFF and you

will require $25632-$bit locations for your vector table.

Please read section $3\mathrm{.}4$ in your TM$4$C$123$GH$6$PM datasheet to help write your

function.

All $155$ original vector addresses must be transfered from the existing table

in Flash memory $($currently at offset $0)$ to the new SRAM location before

updating the vector table offset in the NVIC.

Note that not all of the $25632-$bit locations in the SRAM block will be used.

What advantage is there in relocating an interrupt vector table from Flash

memory to SRAM?
