All flags are affected after the SUB operation to reflect the result of subtraction.
The 8085 was introduced by Intel in 1977.
5 FLAGS
85 is a 8 bit processor,number of flags are 5 and memory capacity is 64KB while 86 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.
OS is compulsary to work properly for any processor including 8085 since OS consist of all the instructions that guides the processor,how to react in certain situations........!
There is no protected mode in the 8085 microprocessor, therefore, there are no instructions that are considered privileged.
The 8085 was given its number as the next version of the 8080. The 5 means that it operates on a single 5 volt power source.
there are 5 flags of intel 8085 are: Carry flag(CY), parity flag(P), Auxiliary Carry flag(AC), Zero Flag(Z), Sign flag(S).
5 stands for 5 volt
The 8085 is an 8 bit processor, so its word length is 8 bits.
In the 8085 microprocessor, the Program Status Word (PSW) contains important flags that reflect the state of the processor. Different instructions can affect these flags, such as the Zero Flag, Sign Flag, Carry Flag, and Parity Flag. For example, arithmetic operations like addition or subtraction can set or reset these flags based on the result of the operation. Consequently, the PSW is essential for conditional branching and decision-making within programs, as it provides the necessary status information determined by the executed instructions.
The Intel 8085 was the successor of the 8080, an early 8 bit processor, used most famously in the Altair. (Microsoft wrote Microsoft BASIC for the 8085 Altair). The boom of home computers took off with the Zilog Z80, a compatible processor but had more features. Today the 8085 isn't used much commercially, the 8051 is a more common 8 bit processor for embedded systems. However the 8085 is extremely popular in engineering schools in the middle east, especially India, as an introductory course to microcomputers.
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.
