    Hi friends could you help me with these questions:-

    Q.1 Interface 2K Byte ROM and 3K Byte RAM with 8085. Memory IC available are
    1K x 8 ROM, 1K x 8 RAM.

    Q.2 Write an instruction sequence in 8087 assembler language that would calculate
    theta and tan theta , where theta is greater than 0 and less than pi/2. Assume that THETA
    contains the angle in the short real format and that the results are to be stored in
    long real format

    Q.3 Construct a lookup table program that converts the hex number in A to an
    equivalent BCD number in registers R4 (MSB) and R5 (LSB) of 8051.

    Thanks In advance

    Q1 is not a question but a statement of fact.

    Q2 & Q3 - what code have you got so far ?

    Q1 looks like it is asking how you would physically wire the memory. Does it mean you have to draw a schematic?

    You're not exactly giving us much to go off of here. Some additional information would be nice, rather than just copying the questions directly from a textbook. What do you not understand, what do you have so far, etc. etc.

    Shouldn't this question go into the Homework section?
