ANSI C SRC Simulator

The ANSI C SRC Simulator

The ANSI C simulator simulates the operation of the SRC computer. It is a functional simulator that executes binary SRC programs, and allows the display of registers and memory. Here is a view of the simulator after executing the command, sim:


______SRC Monitor and Simulator Version 1.0.______

SRC Monitor Commands:
is: Initialize Machine State.
ds: Display Processor State.
cr: Change Reg. Contents. Use cr RegNum HexValue.
cp: Change PC. Use cp HexValue.
dm: Display block of Memory. Use dm HexAddress.
cm: Change a block of Memory words. Use cm HexAddress.
cbm: Change a Block of Memory bytes. Use cbm HexAddress.
dbm: Display a Block of Memory bytes. use dbm HexAddress.
lb: Load a Binary file. You will be prompt for filename.
ss: Single step. Execute one instruction. No arguments.
strt: Start. Start execution at [PC]. No arguments.
q: Quit the simulator.
h: Help. Repeats this message.

(Only first 16K bytes of ram are populated.)

Monitor command: is ds cr cp dm cm cbm dbm lb ss strt q h? lb; load binary file
Name of binary file: tst.bin ; named tst.bin

Monitor command: is ds cr cp dm cm cbm dbm lb ss strt q h? cp 3f0; set PC to start address
Monitor command: is ds cr cp dm cm cbm dbm lb ss strt q h? strt; start the simulation
Monitor command: is ds cr cp dm cm cbm dbm lb ss strt q h? ds; display state after sim
