Compare 8086 microprocessors and 8088 microprocessors?
S.No.8086 Microprocessor8088 Microprocessor1The instruction Queue is 6 byte long.The instruction Queue is 4 byte long.2In 8086 memory divides into two banks, up to 1,048,576 bytes.The memory in 8088 does not divide in to two banks as 8086.3The data bus of 8086 is 16-bit wideThe data bus of 8088 is 8-bit wide.4It has BHE( bar ) signal on pin no. 34 & there is no SSO(bar) signal.It does not has BHE( bar ) signal on pin no. 34 & has only SSO(bar) signal. It has no S7 pin.5The output signal is used to select memory or I/O at M/IO(bar) but if IO(bar)/M low or logic '0' it selects I/O devices and if IO(bar)/M is high or logic '1'it selects memory.The output signal is used to select memory or I/O at M(bar)/IO but if IO/M(bar) is low or at logic '0',it selects Memory devices and if IO/M(bar) is high or at logic '1'it selects I/O.6It needs one machine cycle to R/W signal if it is at even location otherwise it needs two.It needs one machine cycle to R/W signal if it is at even location otherwise it needs two.In 8086, all address & data Buses are multiplexed.In 8088, address bus, AD7- AD0 buses are multiplexed.It needs two IC 74343 for de-multiplexing AD0-AD19.It needs one IC 74343 for de-multiplexing AD0-AD7.
How many lines of the address must be used to access 2048 bytes. How many of these lines are connected to the address input of all chips?
That depends on the memory architecture of the system.if the memory chips are byte wide and not used to create a multibyte bus, 11 address bits are needed.if the memory chips are 32 bits wide, 9 address bits are needed (with the CPU internally selecting which of the 4 bytes it will use).it the memory chips are 64 bits wide, 8 address bits are needed (with the CPU internally selecting which of the 8 bytes it will use.if the memory chips are 4 bits wide, 12 address bits will be needed and the CPU must perform 2 memory cycles per byte that it needs. (yes, I have seen a computer that worked this way!)etc.
What is the difference between the Intel 8080 and the Intel 8085?
The 8086 has 16 bit data bus; the 8088 has an 8 bit data bus. The 8086 has a 6 byte instruction queue, and the 8088 has a 4 byte queue. The 8088 was the chip used in the first IBM PC; the 8086 wasn't used until later models. Since they share the exact same instruction set, which is referred to as the "x86 instruction set" these days, this is often confused. 8085 is a 8 bit processor,number of flags are 5 and memory capacity is 64KB while 8086 is a 16 bit processor ,number of flags are 9 and memory capacity is 1 MB.The main difference between 8085 and 8086 is that 8086 uses pipelining. The 8086/8088 microprocessor is a 16 bt computer, with a 20 bit address bus using a segmented memory architecture. The execution unit architecture, registers, instructions, etc. in both is the same. The bus interface unit on the 8086 is 16 bits wide, where on the 8088 it is 8 bits wide.
What is the size of address bus in 8086?
The address bus in the 8085 is 16 bits wide.
How many address lines are needed to address each machine location in a 2048 X 4 memory chip?
It depends on how wide the data buses are on each chip, and how they're connected. If they're one byte wide, you could need over 256 million addresses, one for each byte. if they're wider, and connected to show an even wider combined data bus, it could be much less; around 32 million.
What is memory organisation?
Memory can be organized into a one-word-wide organization, wide memory organization, interleaved organization and independent memory organization. The types of memory include HDD, RAM, ROM, and GPU.
How do you program 8086?
There are many different instructions and registers in the 8086/8088. The question is too broad. Please ask a more specific question. Alternatively, you can consult a good book, such as "The 8086/8088 Primer", Second Edition, Stephan P. Morse, Hayden Book Company, or any of a wide variety of other books.
What is the explanation for the memory organization of 8086?
Two types of memory organization are used: Linear addressing where the entire memory is available to the processor at all the times ( Motorola 68000 family). Segmented addressing where the memory space is divided into several segments and the processor is limited to access program instructions and data in specific segments.
