| - | ====== ALF Computer 32 ====== | ||
| - | ===== Architecture ===== | ||
| - | The Alfy ASM language is the assembly language for the ALF32 Computer. This virtual CPU has: | ||
| - | |||
| - | * A Harvard Architecture (Program RAM and Data RAM are separate) | ||
| - | * 32 bits instructions | ||
| - | * 64 registers that are 32 bits wide (r0 to r63) | ||
| - | * 49 KB of RAM | ||
| - | * 49 KB of Program RAM | ||
| - | |||
| - | <note>All RAM accesses must be 4 Byte aligned</note> | ||
| - | |||
| - | ===== Simulation ===== | ||
| - | |||
| - | Alfy ASM is simulated using [[http://www.cs.colby.edu/djskrien/CPUSim/|CPUSim]] version 4. To use the simulator: | ||
| - | - Download [[http://www.cs.colby.edu/djskrien/CPUSim/CPUSim4.0.9.zip|CPUSim]] version 4 | ||
| - | - Download the [[https://raw.githubusercontent.com/alexandruradovici/alf-alfy-asm-language-public/master/alf_computer32.cpu|alf_computer32.cpu]] | ||
| - | - Load it into the simulator | ||
| - | |||
| - | To run a simulation, you may run it in interactive or non-interactive mode. | ||
| - | |||
| - | Read the [[http://www.cs.colby.edu/djskrien/CPUSim/Version4InstallationInstructions.txt|installation instructions]]. | ||
| - | |||
| - | ==== Interactive Mode ==== | ||
| - | To run CPUSim, open a shell and write | ||
| - | |||
| - | <code bash> | ||
| - | java -classpath .:richtextfx-fat-0.6.10.jar cpusim.Main -m alf_computer32.cpu -t file.asm | ||
| - | </code> | ||
| - | |||
| - | This will open the UI, load the AlfyComputer_32.cpu and the file.asm. | ||
| - | |||
| - | ==== Non-Interactive Mode ==== | ||
| - | To run CPUSim, open a shell and write | ||
| - | |||
| - | <code bash> | ||
| - | java -classpath .:richtextfx-fat-0.6.10.jar cpusim.Main -c -m alf_computer32.cpu -t file.asm | ||
| - | </code> | ||
| - | |||
| - | This will load the alf_computer32.cpu and run the file.asm. | ||
