|
Core includes a builtin memory type (raw_memory) that is

implemented using an array. raw_memory does not require any

additional functions etc.
|
|
|
|
Callback memory is where the core calls a core device for the data
|
|
it requires. Callback memory can be layered using priorities.
|
|
|
|
Modulo memory is a variation on raw_memory where ADDRESS & (MODULO
|
|
- 1) is used as the index into the memory array.
|
|
|
|
The OEA model uses callback memory for devices.
|
|
|
|
The VEA model uses callback memory to capture `page faults'.
|
|
|
|
BTW, while raw_memory could have been implemented as a callback,
|
|
profiling has shown that there is a biger win (at least for the
|
|
x86) in eliminating a function call for the most common
|
