eight_bit_computer.operations.jump_if_flag_base module

eight_bit_computer.operations.jump_if_flag_base.generate_microcode_templates(src_dest, true_flag_bitdef, false_flag_bitdef)

Generate microcode for all the JUMP_IF_XXX_FLAG instructions.

Parameters:

• src_dest (str) – Name of the module used for both the source and destination.
• true_flag_bitdef (str) – Bitdef that represents the state of the flags if the condition is true, i.e. the operation should jump.
• false_flag_bitdef (str) – Bitdef that represents the state of the flags if the condition is false, i.e. the operation should not jump and just execute the next instruction instead.

Returns:

DataTemplates for all the JUMP_IF_XXX_FLAG instructions.

Return type:

list(DataTemplate)

eight_bit_computer.operations.jump_if_flag_base.generate_instruction_byte_bitdefs(src_dest)

Generate bitdefs to specify the instruction byte

Parameters:src_dest (str) – Name of the module used for both the source and destination. Returns:Bitdefs that make up the instruction_byte Return type:list(str)

eight_bit_computer.operations.jump_if_flag_base.generate_true_control_steps()

Generate control steps to carry out the jump.

Returns:List of list of bitdefs that specify the control steps. Return type:list(list(str))

eight_bit_computer.operations.jump_if_flag_base.parse_line(line, src_dest, name)

Parse a line of assembly code to create machine code byte templates.

If a line is not identifiably a JUMP_IF_XXX_FLAG assembly line, return an empty list instead.

Parameters:

• line (str) – Assembly line to be parsed.
• src_dest (str) – Name of the module used for both the source and destination.
• name (str) – Name of the Operation.

Returns:

List of machine code byte template dictionaries or an empty list.

Return type:

list(dict)

eight_bit_computer.operations.jump_if_flag_base.generate_signatures()

Generate all the argument signatures for the JUMP_IF_XXX_FLAG operation.

Returns:All possible signatures, See get_arg_def_template() for more information on an argument definition dictionary. Return type:list(list(dict))
