How 56 bit key is converted to 48 bit key in des algorithm?
16 (48-bit) subkey are derived from the main key using key schedule.
Main difference between 8085 and 8086?
The most significant difference between the Intel 8085 and 8086 microprocessors is that the 8085 is an 8-bit system and the 8086 is a 16-bit system. This difference allows the 8086 system to have a much larger set of operational instructions and can make calculations to more significant places. Note: the 8085 processor does have two 16-bit registers. The pointer and the program counter.
How can a given number can be checked as even or odd in 8085?
AND it to 1 and test for zero. All even numbers have 0 in the last bit.
What is logic to find the even and odd no without use of modulus and division?
If you're using C, just check the low order bit. In binary, the low order bit of an odd number is 1, and the low order bit of an even number is 0.
What are the maximum positive numbers can be stored in Intel 8085?
The Intel 8085 microprocessor uses an 8-bit data bus and a 16-bit address bus. It can address 64 KB of memory, with each memory location capable of storing a byte. Therefore, the maximum positive number that can be represented in an 8-bit register is 255 (2^8 - 1), while in a 16-bit address space, the maximum is 65,535 (2^16 - 1) when considering the entire memory range.
Why the 16 bit 8085 microprocessor is not possible?
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
How many address bits does 8085 have?
The 8085 has a 16 bit address bus.
How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
What is the Overview of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel Co.
How many 8 bit register in 8085?
There are seven 8 bit registers in the 8085. A, B, C, D, E, H, and L
Which type of architecture 8085 has?
8 bit
Why microprocessor 8085 has 16 bit address lines?
Because that's how Intel designed it. The 8085 is an 8-bit computer operating on a 16-bit address space.
Can you provide an example of a second chance page replacement algorithm in operating systems?
An example of a second chance page replacement algorithm in operating systems is the Clock algorithm. This algorithm works by using a circular list of pages and a "use" bit for each page. When a page needs to be replaced, the algorithm checks the "use" bit of each page in the list. If the bit is set, indicating the page has been recently used, the algorithm clears the bit and moves to the next page. This process continues until a page with a cleared "use" bit is found, which is then replaced.
What is the difference between the Intel 8085 and the Intel 8086?
The Intel 8085 is an 8 bit microprocessor created in 1977.The Intel 8086 is a 16 bit microprocessor created in 1978. The 8086 was the first chip to start the x86 architecture family.8085 contains 16-bit address bus and 8-bit data bus8086 contains 20-bit address bus and 16-bit data bus..In 8085 the clock speed is 3MHZwhere as in 8086 the clock speed is 5MHZ.there are two differences btw 8085&80861. 8086 has 6 byte queue but 8085 has 4 byte queue2. 8086 has 16 bit data bus where as 8085 has 8 bit data bus
How many bits are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
Why 8085 cannot be 16-bit microprocessor?
Because it is an 8-bit microprocessor.
Why is 8085 called so?
because 8085 is one of the landmark of 8-bit microprocessor history. it was more simple in construction than 8080. higher bit microprocessor can be understood very easily if one has prior knowledge of 8085.
