8086 Microprocessor | Set 2
1. The purpose of the microprocessor is to control
2. The first digital electronic computer was built in the year
3. In 1960's texas institute invented
4. The intel 8086 microprocessor is a processor
5. The microprocessor can read/write 16 bit data from or to
6. In 8086 microprocessor , the address bus is bit wide
11. The register AX is formed by grouping
12. The SP is indicated by
13. The BP is indicated by
15. The index register are used to hold
16. The BIU contains FIFO register of size bytes
17. The BIU prefetches the instruction from memory and store them in
18. The 1 MB byte of memory can be divided into segment
20. The CS register stores instruction in code segment
21. The IP is bits in length
22. The push source copies a word from source to
23. LDs copies to consecutive words from memory to register and
24. IMUL source is a signed
25. destination inverts each bit of destination
26. Instruction providing both segment base and offset address are called
27. The conditional branch instruction specify for branching
28. The microprocessor determines whether the specified condition exists or not by testing the
29. The LES copies to words from memory to register and
30. The translates a byte from one code to another code
31. The contains an offset instead of actual address
32. The 8086 fetches instruction one after another from of memory
33. The BIU contains FIFO register of size 6 bytes called .
34. The is required to synchronize the internal operands in the processor CLK Signal
35. The pin of minimum mode AD0-AD15 has address
36. The pin of minimum mode AD0- AD15 has _ data bus
37. is used to write into memory
38. The RD, WR, M/IO is the heart of control for a mode
39. In a minimum mode there is a on the system bus
40. If MN/MX is low the 8086 operates in mode
41. In max mode, control bus signal So,S1 and S2 are sent out in form
42. The bus controller device decodes the signals to produce the control bus signal
43. A Instruction at the end of interrupt service program takes the execution back to the interrupted program
44. Primary function of memory interfacing is that the should be able to read from and write into register
45. To perform any operations, the Mp should identify the
46. The Microprocessor places address on the address bus
47. The Microprocessor places 16 bit address on the add lines from that address by register should be selected
48. The of the memory chip will identify and select the register for the EPROM
49. Microprocessor provides signal like to indicate the read operatio
50. To interface memory with the microprocessor, connect register the lines of the address bus must be added to address lines of the chip.
51. The remaining address line of bus is decoded to generate chip select signal
52. signal is generated by combining RD and WR signals with IO/M
53. has certain signal requirements write into and read from its registers
54. An is used to fetch one address
55. The primary function of the is to accept data from I/P devices
56. signal prevent the microprocessor from reading the same data more than one
57. Bits in IRR interrupt are
58. The pin is used to select direct command word
59. CS connect the output of
60. 8086 and 8088 contains transistors
61. In 8086, Example for Non maskable interrupts are .
62. Access time is faster for .
63. The First Microprocessor was .
64. Status register is also called as .
