Chapter 2-Part1: Internal computer architecture and genuine Mode Softw be Architecture ECP4166- groundbreaking Microprocessors Tutorial 2 Part 1 1. What is the time value of the parallel rule book stored in memory board startle at place B0004H if the line of memory locations B0004H, B0005H, B0006H and B0007H argon 11H, 22H, 33H and 44H respectively? Is this an example of an aligned pronged word or a misaligned double word? How would the decimal material body +127 be stored in the memory starting at address 0B000H? Assume that it is coded in packed BCD piddle and that the least significant digits are stored at the lower addresses. stir how a floating-point value of 178.625 is stored as single precision reliable number? How much memory can be prompt at a time in the 80386DX based microcomputer? How to take off other parts of the 1M memory? enter Segment starts at 10000H, selective information Segment starts at 20000H, and Data Segment (F) starts at 2FFF0H. S pecify (with reason) for severally pair of segments whether they are contiguous, overlapping or disjoint. What happens to the value in IP each time the 80386DX completes an program line fetch? How large is the 80386DXs instruction prefetch queue? In an operation of copying a block of memory to some other location, which registers are helpful in this operation? What is the difference betwixt carry gladiolus and auxiliary carry flag?

What are the aloofnesss of the components of the logical address of the 80386DX in real mode? What is the length of the corresponding tangible address? 2. 3. 4. 5. 6. 7. 8. 9. 10. Find the unknown value for each of the avocation p hysical addresses. a) A000H : ? = A0123H b) ! ? : 14DAH = 235DAH 11. If the current values of SS and SP are C000H and FF00H respectively, how many lyric of data could possibly be held in the stack? If the AX register is pushed on the register now, what memory locations are bear on?
