Does assembly language depend on CPU?
Assembly language (or Assembler) is a compiled, low-level computer language.
It is processor-dependent, since it basically translates the Assembler's mnemonics directly into the commands a particular CPU understands, on a one-to-one basis..

What is assembly language based on?
Assembly language is low-level code that relies on a strong relationship between the instructions input using the coding language and how a machine interprets the code instructions.
Code is converted into executable actions using an assembler that converts input into recognizable instructions for the machine..
What is meant by assembly language in 8085 microprocessor?
An assembly language is a low-level programming language for microprocessors and other programmable devices.
It is not just a single language, but rather a group of languages.
An assembly language implements a symbolic representation of the machine code needed to program a given CPU architecture..
What is the Intel 8085 microprocessor based on?
The 8085 is a conventional von Neumann design based on the Intel 8080.
Unlike the 8080 it does not multiplex state signals onto the data bus, but the 8-bit data bus is instead multiplexed with the lower eight bits of the 16-bit address bus to limit the number of pins to 40..
What is the word length of an 8085 microprocessor?
The data bus also works as address bus when multiplexed with lower order address bus.
Data bus is 8 Bits long.
The word length of a processor depends on data bus, thats why Intel 8085 is called 8 bit Microprocessor because it have an 8 bit data bus..

When was Intel 8085 introduced?
The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976..
Programming Model of 8085:
The programming model of 8085 consist of an 8-bit accumulator, one flag register, 6 general 8-bit purpose registers, and two 16-bit special purpose registers.
These registers are critically required when programming a 8085 processor.
The Intel 8085 is an 8-bit microprocessor introduced by Intel in 1977.
It was binary compatible with the more-famous Intel 8080 but required less supporting hardware, thus allowing simpler and less expensive microcomputer systems to be built.
The Intel 8085 was an 8-bit microprocessor developed by Intel and released in 1976 and was an evolutionary successor to the popular 8080, which can be considered as the chip that launched the PC into the mainstream.

8085 has 246 instructions.
Each instruction is represented by an 8-bit binary value.
These 8-bits of binary value is called Op-Code or Instruction Byte.,Answer: The assembly programming language is a low-level language which uses mnemonics or symbolic codes as instruction, for example: ADD, SUB ,Develop a program to add two numbers of 8 byte long whose result is more than 8 byte.
The first number is stored from 7501 to 7508 and the second number is ,Machine independent languages are called – High-level languages – For e.g.

How does the 8085 evaluate a condition?

The 8085 evaluates the condition while it fetches the second instruction byte. If the specified condition is not satisfied
The 8085 skips over the third instruction byte and immediately fetches the next Instruction. Skipping the unnecessary byte allows for faster execution.

How many inputs does a 8085 processor have?

The 8085 processor Includes four hardware inputs that generate internal RST instructions. Rather than send a RST instruction
The interrupting device need only apply a signal to the RST5.5

RST6.5

8-bit microprocessor

The Intel 8008 is an early byte-oriented microprocessor designed by Computer Terminal Corporation (CTC)

Implemented and manufactured by Intel

And introduced in April 1972.It is an 8-bit CPU with an external 14-bit address bus that could address 16 KB of memory.Originally known as the 1201

The chip was commissioned by Computer Terminal Corporation (CTC) to implement an instruction set of their design for their Datapoint 2200 programmable terminal.As the chip was delayed and did not meet CTC's performance goals

The 2200 ended up using CTC's own TTL-based CPU instead.An agreement permitted Intel to market the chip to other customers after Seiko expressed an interest in using it for a calculator.

8-bit microprocessor

The Intel 8080 (eighty-eighty) is the second 8-bit microprocessor designed and manufactured by Intel.
It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility.
The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4, 5, 7, 10, or 11 cycles.
As a result, the processor is able to execute several hundred thousand instructions per second.
Two faster variants, the 8080A-1 and 8080A-2, became available later with clock frequency limits of 3.125 MHz and 2.63 MHz respectively.\nThe 8080 needs two support chips to function in most applications: the i8224 clock generator/driver and the i8228 bus controller.
It is implemented in N-type metal–oxide–semiconductor logic (NMOS) using non-saturated enhancement mode transistors as loads thus demanding a +12 V and a −5 V voltage in addition to the main transistor–transistor logic (TTL) compatible +5 V.

File format for conveying binary information

Intel hexadecimal object file format

Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form

Making it possible to store on non-binary media such as :

Paper tape
Punch cards
Etc.

To display on text terminals or be printed on line-oriented printers.The format is commonly used for programming microcontrollers

EPROMs

And other types of programmable logic devices and hardware emulators.In a typical application

A compiler or assembler converts a program's source code to machine code and outputs it into a HEX file.Some also use it as a container format holding packets of stream data.Common file extensions used for the resulting files are .HEX or .H86.The HEX file is then read by a programmer to write the machine code into a PROM or is transferred to the target system for loading and execution.

Each time Intel launched a new microprocessor

They simultaneously provided a system development kit (SDK) allowing engineers

University students

And others to familiarise themselves with the new processor's concepts and features.The SDK single-board computers allowed the user to enter object code from a keyboard or upload it through a communication port

And then test run the code.The SDK boards provided a system monitor ROM to operate the keyboard and other interfaces.Kits varied in their specific features but generally offered optional memory and interface configurations

A serial terminal link
Audio cassette storage

And EPROM program memory.Intel's Intellec development system could download code to the SDK boards.
