What is the difference between microprocessor 8086 and 8088?
8086 is a 16-bit microprocessor with a 16-bit data bus; 8088 has an 8-bit data bus. Data bus width is the only major difference. Figure 9–1 (a) The pin-out of the 8086 in maximum mode; (b) the pin-out of the 8086 in minimum mode. Both microprocessors require +5.0 V with a supply voltage tolerance of +10 percent.
Why is 1MB size 8086?
It means that in 8086, the addresses used in programs (the logical or virtual address as you call it) are 16 bits but the actual address that 8086 sends to the RAM is 20 bits. Why? Because 16 bits = 64 KB of address space where as 20 bits of address = 1 MB of memory.
Is 8086 still manufactured?
Though possibly an 8186 would be OK. Your problem is that unlike 80186 or 80386, 8086 was discontinued early in the 90s and it wasn’t as popular at the time.
What is the difference between 8085 microprocessor and 8086 microprocessor?
The 8086 is a register based 16-bit microprocessor which can process 16-bit of data at a time. The 8085 microprocessor is an 8-bit accumulator based microprocessor. The 8086 microprocessor is a 16-bit general purpose register based microprocessor. The 8085 microprocessor has a data bus of 8-bit size.
What is 16bit data?
A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.
Why is data bus 16-bit?
During reading, data are always handled as 16 bits without distinguishing between 8- and 16-bit data. Sixteen bits are read even if the MOV. B instruction is used for reading from the memory. Non-used 8 bits are not read into the CPU although they are output from the memory.
What is the difference between an 8086 and 8088 microprocessor?
The 8086 (also called iAPX 86 ) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs ),…
Where was the 8088 processor designed?
The 8088 was designed at Intel’s laboratory in Haifa, Israel, as were a large number of Intel’s processors.
What does 8088 stand for?
The Intel 8088 (” eighty-eighty-eight “, also called iAPX 88) microprocessor is a variant of the Intel 8086. Introduced on June 1, 1979, the 8088 has an eight-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range are unchanged, however.
What is the maximum clock speed of an 8088?
Variants of the 8088 with more than 5 MHz maximal clock frequency include the 8088-2, which was fabricated using Intel’s new enhanced nMOS process called HMOS and specified for a maximal frequency of 8 MHz. Later followed the 80C88, a fully static CHMOS design, which could operate with clock speeds from 0 to 8 MHz.
