Part $2$

Exercise $1$

Figure $1$ below shows the block diagram of a processor Integrated Circuit $($IC$).$

Figure $1$

$1-$ Is the processor a microprocessor or microcontroller?

$1-$ Is the processor a microprocessor or microcontroller?

Justify your answer.

The processor is: Microprocessor $/$ Microcontroller

Justification;

$2-$ How many address lines are there required for the Flash Memory?

There are address lines for the Flash Memory

$3-$ How many address lines are there required for the the SRAM memory?

There are address lines for the SRAM memory

$4-$ The processor is a $16$ bits processor. Does the processor require more instructions than the Cortex M$0+$ processor to perform $32$ bits additions when the operands are stored in CPU internal registers?

Justify your answer.

$4$

The processor requires more clock cycles:

True$/$False

Justification;

$5-$ The Flash memory is a kind of RAM memory:

True$/$False

$6-$ Which of the following address ranges are possible for the Flash memory?

Select ALL applicable.

a$-$ From $0100$ to $01FFF$

b$-$ From $03000$ to $03$ FFFFF

c$-$ From $05000$ to $08FFF$

d$-$ None of the above

$7-$ The Booting address of the processor is $02FFF.$ Which of the following address ranges can't be allocated to the RAM memory?

Select ALL applicable.

a$-02000$ to $023FF$

b$-01000$ to $013F$

c$-.0000$ to $03FF$

d$-$ All of the above

e$-$ None of the above

$8-$ What can be true about the Program Counter Register of this processor?

a$-$ It can be $4$ bits width

b$-$ It can be $8$ bits width

c$-$ It can be $9$ bits width

d$-$ None of the above

$9-$ Is it possible to interface the processor to an analog sensor$?$

Select: Possible$/$Not possible.

$10-$ The CPU has a multiplier that accepts two $16$ bits operands and store the results into $24$ bits special function register. For the multiplication of two unsigned numbers A and $B,$ what would be the maximal value of $B$ to avoid an overflow if $A=2^{14}?$
