Hi friends please help me in solving 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
sin 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.
