* add a Signal struct which records its val and prev val, and can be used for state change things like interrupts
|
|
the int controller coild have multiple for different prioritis, and could maybe be activated by multiple sources
|
|
* the remaining issue with the shell is that putchar_buffered requires the TX interrupt and TX enable/disable commands to work in order to trigger a write
|
|
|
|
|
|
* how will you add the cpu, which is not addressable, but is steppable, and also interruptable... what else?
|
|
* should you simulate bus arbitration?
|
|
* if the bus had an Rc<RefCell<Box<dyn AddressableDevice>>>, then it could be like AddressSpace used to be, with it's own Addressable, and then you could
|
|
access one of multiple busses to do an op on it, rather than a single bus per machine
|
|
* can you get rid of the duplicate read/write functions in System?
|
|
|
|
* how do you pass in a mutable system to a mutable device? At the very least, I need the AddressSpace, but that needs access to the devices/memory segments.
|
|
I could make System contain refcells for submutability

|
* check all instructions in the docs
|
|
|
|
* make tests for each instruction
