Question

Draw a decode circuit of 32K X 8 RAM with one ORgate for address
decode.

The number of address lines to be decoded is 20. Please indicate
the address map obtained by this decode method. The address range
of this memory chip is 0000 to 07FFF.

Consider a memory system with a 16 bit address and the following
address decode logic. The signals enrom, enram, and endev are the
device enable signals for ROM, RAM, and I/O devices,
respectively.
◦ csrom <= '1' when ax(15 downto 12 = "1101" or ax(15 downto
13 = "111" else '0';
◦ csram <= '1' when ax(15 downto 13) = "001" or ax(15 downto
12) = "0100" else '0';
◦ csdev <= '1' when ax(15 downto 8) = "00001" else...

Design a 512K x 8 Static RAM (SRAM) module. You do not need to
draw the entire circuit. Describe which components are used and how
each component should be connected. Small drawings that describe an
iterative process should be enough.

*
17
19
16
15
20
14
18
2-Which of the following instructions requires (BYTE PTR)?
*
SHR [500H], 3h
LDS SI, [1000H]
LAHF
PUSH [9AAH]
ADD AX, [800H]
3-Where are the interrupt vectors located in the
microprocessor’s memory? *
