GATE IN 2021 | Question: 11
A $16$-bit microprocessor has twenty address lines ($A_{0}$ to $A_{19}$) and $16$ data lines. The higher eight significant lines of the data bus of the processor are tied to the $8$-data lines of a $16$ Kbyte memory that can store one byte in each of its $\text{16K}$ address locations.The memory chip ... only $A_{19}$ to $A_{14}$ for generating chip select The above chip cannot be interfaced as the width of the data bus of the processor and the memory chip differs

The address lines $A_9 \dots A_2$ of a 10 bit, 1.023 V full-scale digital to analog converter $(DAC)$ is connected to the data lines $D_7$ to $D_0$ of an 8-bit microprocessor, with $A_1$ and $A_0$ of the $DAC$ grounded. Now, $D_7 \dots D_0 $ is changed from $\text{1010 1010 to 1010 1011}$. The corresponding change in te output of the $\text{DAC (in mV, rounded off to one decimal place)}$ is __________.

In a microprocessor with a 16 bit address bus, the most significant address lines A15 to A12 are used to select a 4096 word memory unit, while lines A0 to A11 are used to address a particular word in the memory unit. If the 3 least significant lines of the address bus A0 to A2 are short-circuited to ground, the addressable number of words in the memory unit is $\_\_\_\_\_$.

A portion of an assembly language program written for an 8-bit microprocessor is given below along with explanations. The code is intended to introduce a software time delay. The processor is driven by a $5\; MHz$ clock. The time delay (in $\mu$s) introduced by the program is _____________. $\text{MVI B, 64H}$ : Move ... : Jump to address with Label LOOP if zero flag is not set. Takes $10$ clock periods when jump is performed and $7$ clock periods when jump is not performed.
