"Intel4004"
| "Intel4004" an emulator of Intel's 4004 (MCS-4) computer architecture. | |
▪
Creating a virtual machine instance:
create a new instance of the Intel 4004 virtual machine | ||
create an Intel 4004 instance with roms rams |
▪
▪
For the virtual machine, the following properties can be queried:
"Intel4004"
obj["CycleCount"] | the number of cycles the machine has run | |
obj["ProcessorState"] | ||
obj["RAMBankCount"] | the number of RAM banks | |
obj["RAMChipCount"] | the number of RAM chips | |
obj["RAMState"] | ||
obj["ROMArrayVisualization",chip] | a visualization of the chip | |
obj["ROMChipCount"] | the number of ROM chips | |
obj["ROMState"] | ||
obj["StepCount"] | the number of steps the machine has run |
▪
For the virtual machine, the following commands can be executed using :
"Intel4004"
return an interactive debugger | ||
reset the state of the processor, setting the program counter to org | ||
reset the specified RAM chip bank | ||
reset the machine | ||
load the binary bin chip | ||
VirtualMachineExecute[obj,"ROMReset",chip] | reset the specified ROM chip | |
run n | ||
run n |

Create a new instance of the virtual machine:
"Intel4004"
In[1]:=
intel4004=
["Intel4004"]
 | VirtualMachine |
Out[1]=
VirtualMachineObject
 |  |
|
Get information about the object:
In[2]:=
Information[intel4004]
Out[2]=
VirtualMachineObject | |||||||||
|
Obtain the state of the processor:
In[3]:=
intel4004["ProcessorState"]//Dataset
Out[3]=
Load a program (in the first ROM chip) that tests RAM related instructions:
In[4]:=
 | VirtualMachineExecute |
|
Out[4]=
VirtualMachineObject
| |
|
Verify the program has correctly loaded:
In[5]:=
intel4004["ROMArrayVisualization",0]
Out[5]=
Get the state of the registers of the first RAM chip in the first RAM bank:
In[6]:=
intel4004["RAMState"][0][0]["Register"]//Dataset
Out[6]=
Run the machine for 1000 steps:
In[7]:=
| VirtualMachineExecute |
Out[7]=
VirtualMachineObject
| |
|
The program has correctly modified the contents of the RAM array:
In[8]:=
intel4004["RAMState"][0][0]["Register"]//Dataset
Out[8]=
