The project is to implement SIC/XE assembler that produces code for the absolute loader used in the SIC/XE programming assignments.

In phase 1 of the project, it is required to implement Pass1 of the assembler. The output of this phase should be used as input for subsequent phase.

In phase 2 of the project, We are going to build on the previous phase and use its output to implement pass 2 of the assembler.

install NetBeans IDE.

1. Built a parser that is capable of handling source lines that are instructions, storage declaration, comments, and assembler directives (a directive that is not implemented should be ignored possibly with a warning).

2. For instructions, the parser is to minimally be capable of decoding 2, 3 and 4-byte instructions as follows:

a) 2-byte with 1 or 2 symbolic register reference (e.g., TIXR A, ADDR S,A)

b) RSUB (ignoring any operand or perhaps issuing a warning).

c) 3-byte PC-relative with symbolic operand to include immediate, indirect, and indexed addressing.

d) 3-byte absolute with non-symbolic operand to include immediate, indirect, and indexed addressing.

e) 4-byte absolute with symbolic or non-symbolic operand to include immediate, indirect, and indexed addressing.

3. The parser is to handle all storage directives (BYTE, WORD, RESW, and RESB).

4. The output of this phase should contain (at least):

a) The symbol table.

b) The source program in a format similar to the listing file.

c) A meaningful error message should be printed below the line in which the error occurred.

1. The output of the assembler should include:

a) Object-code file.

2. The assembler should support:

a) EQU and ORG statements.

b) Simple expression evaluation. A simple expression includes simple (A B) operand arithmetic, where is one of +, -, *, / and no spaces surround the operation, eg. A+B.
