The main differences between an 8085 and an 8086 microprocessor are the size of the data lines, the clock speeds, the way the memory space is organized and the instruction queue. These differences affect the way that the processors function and the way that they are used for different tasks.
The 8085 microprocessor is smaller than the 8086 microprocessor in relation to the number of data lines that are available. The 8085 has 8 bits of space available while the 8086 has 16 bits available. The clock speed for all 8085 microprocessors remains at 3 megahertz. Depending on the model of the 8086 microprocessor, the clock speed can be 5, 8 or 10 megahertz. Despite the model of the processor, the clock speed of the 8086 is higher than the clock speed of the 8085.
The way that the memory is organized in the processors is different because the 8085 models do not support memory segmentation. The 8086 supports and only organizes memory space using the memory segmentation process. The 8086 model also allows an external processor to be used, but it can run on its own. The 8085 does not allow the use of an additional external processor and only functions on its own.Learn More
The CPU is known as the central processing unit, and this term is synonymous with microprocessor. The microprocessor is considered the brain of the computer, and Intel invented the term in 1971. There was a previous 8-bit chip developed in 1969 known as the Four-Phase AL1; however, Intel invented a better component and coined the term microprocessor.Full Answer >
There are five primary microprocessor types: complex instruction set microprocessors, reduced instruction set microprocessors, superscalar processors, application-specific integrated circuit processors and digital signal multiprocessors. A microprocessor is a part of a computer, and it is made out of tiny transistors, circuit parts and a microchip or solo semi-conductor.Full Answer >
The three functions of a microprocessor are controlling the operations of a computer’s central processing unit, transferring data from one location to another and doing mathematical calculations using logarithms. A microprocessor is thought to function like a human brain and is essential in the operation of computers and digital devices.Full Answer >
One of the features on an Intel 8085 microprocessor is an eight-bit microprocessor that can process, provide and accept eight-bit data simultaneously, as well as being able to access 64 kilobytes of memory using 16 built-in address lines and providing five built-in hardware interrupts. The Intel 8085 can also operate on a 5-volt power supply and access 256 I/O ports by providing eight-bit I/O addresses.Full Answer >
