The input sequential code files allows the user to easily define a sequential code with any text editor. The .pla extension is required for all code files.

Characteristics

File must be created with the following characteristics:

• The first line (not a commentary) must contain the number of instructions of code.
• Each instruction must be placed in a new line.
• Operands are separated with blanks or tabs.
• Labels must be placed at the start of the line and always finishes with a ":".
• Commentaries start with "//". From here to the end of the line will be considered as a commentary.

Instructions

The instructions are inspired in the MIPS IV repertory. We use the next nomenclature:

• Rn General Purpose Register n.

    f. i.  R1, R0...
  

• Fm Floating Point Register m.

    f. i.  F1, F0...
  

• n Inmediate value n.

    f. i.  #12, #0...
  

• n(Rm) Memory address.

    f. i.  (R1), 3(R4)...
  

• LAB: Branch destiny label.

    f. i.  LOOP1:, END:...
  

The allowed instructions are:

• ADDI Rn Rm #i
• ADD Rn Rm Rp
• SUB Rn Rm Rp
• AND Rn Rm Rp
• OR Rn Rm Rp
• NOR Rn Rm Rp
• XOR Rn Rm Rp
• SLLV Rn Rm Rp
• SRLV Rn Rm Rp
• MULT Rn Rm Rp
• ADDF Fn Fm Fp
• SUBF Fn Fm Fp
• MULTF Fn Fm Fp
• LW Rn i(Rm)
• LF Fn i(Rm)
• SW Rn i(Rm)
• SF Fn i(Rm)
• BNE Rn Rm LAB
• BEQ Rn Rm LAB
• BGT Rn Rm LAB
