1- Explain what happens when PUSH Bx instruction executes. Make sure to show where BH and BL are stored (assume that SP-0100h and SS-0200h)

'Clock The given 4 bit serial in parallel output register is loaded with 1011.If contnpusly clock is applied the after how many clock pulse data become 1011 again?

1. Write down 2- differences between  Von-Neumann and Harvard architecture. 2. you are executing an instruction, SUB $s0, $s1, $s2 (address 0x20). Draw the datapath of this instruction when $s1=10, $s2=5. When are the stages in this datapath? Mark the components which are active in corresponding stages. 3. How to store(1050000)10 in register $s0? Write down the instructions that stores the data in $s0 register.

What other options are there besides OUTPUT for the pinmode instruction?

a) An 8-bit shift register holds the data word 00111100. What will the register contents be after three right shifts? (Assume that serial input=D0) b) Draw the above shift register circuit using negative edge triggered D FFs

(c) Draw the schematic and describe the operation of a 4-bit SIPO shift register.

Solve the following question. You must show your work. a) What does 962F000016 represent in an IEEE single-precision floating-point number? b) Convert -151o to a 16-bit sign-magnitude representation. c) Convert-151o to a 16-bit two's complement representation. d) Define the system status register value after an instruction execution resulted the following: a. Result was a non-zero value, a negative value, had a carry and extended bits. b. Trace mode was not on and was executed in supervisor mode. C. Any higher interrupt priorities higher than level 3 will be recognized.
