DLS file and DLX file and commands

DLS file is Source file
File created by user and Input of Assembler DSAM

DLX file is Executable file
File created by Assembler if the file assemble. It can be run from DLX simulator

>>java -jar dasm.jar  try.dls -a
-a Program follows absolute address

>>java -jar dasm.jar  try.dls -a -l
-l List down the error & assembly of your program

Introduction to DLX Machine

DLX Machine architecture

• DLX machine consists of 32 registers from r0 to r31

r0 always 0
r31 Jr Register
r1 to r30 can be used for program

• DLX machine RAM depends on dsim.cfg file

dsim.cfg file contains.

dsim new bus dsim.bus.Bus 

dsim new cpu dsim.dlxcpu.Dlxcpu
dsim connect bus$slot0 cpu$dlxbus

dsim new ram dsim.ram.Ram 00000 4000
dsim connect bus$slot2 ram$dlxbus

In this case, DLX machine consist of Ram upto 4000 from 0 (Ex 0,4,8,12..4000)

• DLX machine consists of IO Devices includes switches and lights

Address of lights and switches depends on dsim.cfg file

dsim new lights dsim.lights.Lights FFFFFFF8

dsim connect bus$slot1 lights$dlxbus

dsim new switches dsim.switches.Switches FFFFFFFC

dsim connect bus$slot3 switches$dlxbus

Address for lights      :FFFFFFF8
Address for switches:FFFFFFFC
