How many type of instructions does the 32-bit Intel 8086 have?
The Intel 8086/8088 is not a 32 bit machine. It is a 16 bit machine. It has 72 instruction types.
Difference between 8086 and 80386?
There are several differences between the 8086 and the 80386. Two notable differences: 1.) the 8086 is a 16 bit computer, while the 80386 is a 32 bit computer, and 2.) the 8086 does not support virtual addressing while the 80386 does.8086 is 8 bit processor and 80386 is 16 bit processor
What is higher order address of a 16 bit address?
In the 8085, the high order address is A8-A15. In the 8086/8088, the high order address is A8-A19. (For a 16-bit address, the answer is A8-A15, but the answer above reflects the chosen categories, 8085 and 8086/8088, with the 8086/8088 running in 20-bit mode.) In Windows XP, running in 32-bit mode, the high order address is A8-A31, a 32 bit address.
Size of data bus in 8086?
It is my understanding that the 80286 has a 16-bit data bus. This was a doubling of the original 8086/8088 processors.
Maximum RAM capacity of 8086 processor?
The 8086/8088 can address a maximum of 220, or 1,048,576, or 1 MB of memory.
What is the difference between 16 bit compilers and 32 bit compilers in C?
16 bit compilers compile the program into 16-bit machine code that will run on a computer with a 16-bit processor. 16-bit machine code will run on a 32-bit processor, but 32-bit machine code will not run on a 16-bit processor. 32-bit machine code is usually faster than 16-bit machine code.-DJ CraigNoteWith 16 bit compiler the type-sizes (in bits) are the following: short, int: 16long: 32long long: (no such type)pointer: 16/32 (but even 32 means only 1MB address-space on 8086)With 32 bit compiler the object-sizes (in bits) are the following:short: 16int, long: 32long long: 64pointer: 32With 64 bit compiler the object-sizes (in bits) are the following:short: 16int: 32long: 32 or 64 (!)long long: 64pointer: 64[While the above values are generally correct, they may vary for specific Operating Systems. Please check your compiler's documentation for the default sizes of standard types]Note: C language itself doesn't say anything about "16 bit compilers" and "32 bit compilers"
What is the meaning of PC Mac OS and x86 x64 in computer language?
PC = Personal Computer. Mac OS = the Operating System used by Apple's Macintosh computers. X86 = A 32 bit processor. Originally the name came from Intel's 8086 processor which was a 16 bit processor but the name X86 is now used to denote a processor that can handle 32 bit and 16 bit instructions. X64 = A 64 bit processor sometimes known as an X86-64 as they can handle 16, 32 and 64 bit instructions.
What is the difference between 32- bit drivers and 16 -bit drivers?
32 bit drivers are designed for 32 bit computers. 16 bit drivers are designed for 16 bit computers. Most modern computers are either 32 or 64 bit.
Why you Use Memory Segmentation In 8086 Microprocessor?
The 8086/8088 is a 16 bit processor running on a 16 bit (8086) or 8 bit (8088) bus with a 20 bit address bus. In order to obtain the extra 4 bits of addressibility, Intel designed segment registers that are effectively multiplied by four and then added to the 16 bit offset address generated by the instruction. This yields 64K segments of 64KB each, although they overlap each other at a distance of 16 bytes.
What is 16 bit or 32 bit?
This refers to how the CPU processors the information, 32 bit is more current than 16 bit and much faster. 16 bit is obsolete because we not gave 64 bit systems.
What are preferable to use 32-bit drivers or 16-bit drivers?
Assuming you are running a 32 bit (modern) operating system, 32.
What may the reson for developing an external 8 bit processor like 8088 along 8086 multiprocessing and management?
The 8088 is an 8 bit bus implementation of an 8086, which is a 16 bit processor. The reason for providing the 8088 variant is simply to minimize the hardware cost and complexity of designing a system to use the 8088. This is the approach used for the first IBM PC. Some implementations, such as the Tandy 1000SX, used the 80186, a highly integrated version of the 8086, in a 16 bit bus configuration. Later versions, in order to increase performance, went ahead and provided 32, 64 and 128 bit bus implementations of advanced processors.And, no, the 8086 is not a multiprocessing computer. It is a single processor. Intel did not get into multiprocessing until the Xeon and the Pentium IV.
