First the word in memory location is fetched and which will give the address of the operand. Identifiers, keywords, constants, operators and punctuation symbols such as commas and parentheses are typical tokens. In the numeric format if the sign appears in the last byte it is known as the trailing numeric. E Civil 5th Semester Question There is no need to refer memory.

ADD 6 immediate to R indirect Here 6 is the immediate data and the next value is indirect data. Linkin The re Time g loader editor the pro location and linking is performed each It produces a linked version of a program and Here t h gram is loaded whichis written in a file for later execution e loading can be accomplished in a single Two passes are required It is used to store the name and address of the each external symbol.


Features that a basic text editor should posses 4. Here the address of the operand is 5 and its corresponding value is 7. Describe the various stages of an assembly process and explain how they are organized in two pass assembler. If the questiob is byte addressable then the address assigned for the next symbol is Describe the architecture of SIC machine. What is the function performed in editing phase?


What is error handler? Newer Post Older Post Home. Explain ii Discuss the nature of user interface for an interactive debugger. Register direct, register deferred, auto increment and amswers, program counter relative, base relative, index register mode and indirect addressing are the various addressing modes in VAX architecture.

ADD R5, [] Here the second operand is given in indirect addressing mode. The symbol table includes the name and value for each symbol in the source program,together with flags to indicate error conditions.

A-accumulator Used for arithmetic operation.

End record marks the end of the object program and specifies the address in the program where execution is to begin. The operation code table contain the mnemonic operation code and its machine language equivalent. Interpreter is a set of programs which bxnk high level language program to machine language program line by line. One pass assembler that generate their object code in memory for immediate execution is known as load and go assembler. This variable is used to assign addresses to the symbols.

During the translation first the object code is converted into its corresponding machine language equivalent with the help of OPTAB.

What are the phases in performing editing process? Macro processor is system software that replaces each macroinstruction with the corresponding group of sjstem language statements. The operation given in the instruction sysgem performed and the result is stored in the accumulator register.

What is the result of the following statement? In the case of register to register instructions the operand field contains the register name. Define conditional macro expansion. Environmental science and engineering Questions B Define absolute loader The loader, which is amswers only for loading, is known as absolute loader.

What is meant by general-purpose macro processors? Draw SS instruction format. Name some of text editors. Control sections are most often used for subroutines. Listing printed — PASS2 d. Loading — brings the object program into memory for execution Relocation — modifies the object program so that it can be loaded at an address different from the location originally specified Linking — combines two or more separate object programs and also supplies the information needed to reference them.

In case of nested macro calls the expansion of the latest macro call is completed first. Discuss the design aspects of a two pass assembler. What is the need of MAR register. What is conditional assembly?

Far jump A far jump is a jump to a target in a different code segment and it is assembled by using different segment registers.

The execution of nested macro call follows the LIFO rule.

Define load and go assembler. Discuss about any one of the RISC machine architecture. Operating system acts as an interface between the user and the system Eg: In this addressing mode the operand value is given directly. Explain conditional macro expansion with different types of macro conditional statements. This record gives information about external symbols that are defined in a particular control section.

What is meant by program relocation? Such references between control are called external references. How to request Study Znswers Anna University Department of Civil Engineering B.
