# 07 Operating System
|
||
|
|
|
||
|
|
To run serious application like Tetris we need the operating system JACK-OS, written in the high level language JACK.
|
||
|
|
|
||
|
|
For every JACK-OS class we provide a skeleton file, with the signatures of functions and methods. In the dedicated test folder you find implementation details and test classes.
|
||
|
|
|
||
|
|
The folder `00_HACK` contains a simulation of HACK similar to the one in `06_IO_Devices/00_HACK` with the following differences:
|
||
|
|
|
||
|
|
* uses build in chips from `01_Boolean_Logic` to `03_Sequential_Logic` instead of going down to the nand gate level.
|
||
|
|
* has 64k words of instruction ROM preloaded with JACK-OS and applications
|
||
|
|
* is not uploadable to iCE40HX1K-EVB
|
||
|
|
|
||
|
|
## Simulation of JACK-OS classes
|
||
|
|
|
||
|
|
Use `00_HACK` of `07_Operating_System` to test your JACK-OS classes in simulation.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd <test folder>
|
||
|
|
$ make
|
||
|
|
$ cd ../00_HACK
|
||
|
|
$ apio clean
|
||
|
|
$ apio sim
|
||
|
|
```
|
||
|
|
|
||
|
|
## Run JACK-OS in real hardware on iCE40HX1K-EVB
|
||
|
|
|
||
|
|
To test JACK-OS on real hardware iCE40HX1K-EVB use the design of HACK developed in `06_IO_Devices` with the bootloader of `05_GO`. Attach iCE40HX1K-EVB to your computer and run the following commands:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd <test folder>
|
||
|
|
$ make
|
||
|
|
$ make upload
|
||
|
|
```
|
||
|
|
|
||
|
|
This will compile all classes in the test folder and upload the binary file to SPI flash rom starting at address 64k (0x010000), where the bootloader can find it.
|
||
|
|
|
||
|
|
**Attention:** All used classes must be linked to the folder in which you run the compiler. To add the class `<JACK-OS class>.jack` simply make a soft link in the working directory:
|
||
|
|
|
||
|
|
Finally you can run Tetris!
