Intel 8086 and 8088

The Intel 8086/8088 family of microprocessors is a 16 bit architecture on a 16 bit (8086) or an 8 bit (8088) bus. The 8088 was the processor in the original IBM PC, and has evolved into the most popular processor used today in PC's and servers.

What is the main difference between 8086 and 8088 microprocessor according to the pin configuration?

The 8086 has a 16 bit bus, while the 8088 has an 8 bit bus. In both A0 through A7 are shared as D0 through D7. The the 8086, A8 through A15 is also shared as D8 through D15.

Define external record?

External record is simply defined as case of data that is collected from outside. This is commonly used as a representation of proof in form of external files.

What is 3 byte instruction in microprocessor?

A two-byte instruction gives the specific function instruction in two bytes, or two words. The first specifies the opcode, which tells the microprocessor what operation will occur. The second specifies the operand, or the data that the operation is done on.

What is Delta Air lines corporate address?

The Delta Airlines company headquarters is located in Atlanta, Georgia, USA. However, the address they provide on their official website is only a post office box and does not actually pinpoint a precise location. The address they provide is PO Box 20706, Atlanta GA, 30320-6001.

What a brief description do you have of the type of position you desire?

Give a brief description of the type of employment or position you desire.Give a brief description of the type of employment or position you desire.

Ora a is executed in intel 8085 microprocessor?

The ORA A instruction does not change the contents of the accumulator. It does, however, set flags to indicate something about the value of the accumulator. In particular, Z means the result is zero, N means it is negative, and P means it has an odd number of ones.

Why 7 segment display is used in microprocessors?

A 7 segment display is an I/O device, and it is not necessarily used in microprocessors. The choice of I/O devices is a function of system design, not microprocessor design.

Why 8086 takes two cycles to fetch the data from odd address?

The 8086 takes two cycles to fetch words from an odd address because the Bus Interface Unit (BIU) actually only deals with words, which are two bytes at an even address. If you perform an operation on a byte, the BIU will do a word operation, but it will leave the other byte alone. If you perform a word operation at an even address, the BIU can do the operation in one cycle. If the word, however, is at an odd address, the BIU must use two cycles, leaving the respective "other" byte alone in each case. For performance sake, always align your data with the bus design.

What is load effective address?

Load effective address, in assembler terms, and in the case of for example "lea eax, [esp-8]" means "please compute and put the address of [esp-8] into the register eax".

In other terms, "mov" works only on values, except you tell it to get the address of your source arg (you could do mov eax, offset [ebp-8]), while "lea" works on addresses only.

How the Memory Management Unit converts the logical addresses to physical addresses?

In the 8086/8088, the logical address corresponds to a segment register, such as CS (Code Segment), DS (Data Segment), SS (Stack Segment) and ES (Extra Segment). The segment register is selected by context, or it is explicitly selected using a segment override prefix. The segment register is left shifted 4 bits into a 20-bit temporary register. This is the same as multiplying it by 16. Then the logical address is added to that result. The final result is the physical address.

What is logical and physical server?

Physical servers (also referred to as boxes) are represented by physically or virtually separate computers with their own operating systems (Linux, FreeBSD Unix, or Windows).

If DS equals 3458H SI equals 13DCH calculate the physical address?

If DS equals 3458H and SI equals 13DCH, the physical address is 3595CH.

Multiply DS by 16, by left shifting it 4 - 3458H becomes 34580H - then add 13DCH to get 3595CH.
