-== Internal detail of the EE recompiler ==
+== Memory And Buffer ==
 An important part of the recompiler is the management of various blocks (x86/EE etc...). You can see below a nice schematic with the links between them.

 '''Important note:''' those LUTs are based on the TLB mapping at the boot of the EE kernel. They don't take TLB updates into consideration. It won't work if your game/program (linux/home-brew) relies on TLB management. In this situation your best bet is to use the interpreter.

-Basically the RAM memory is splitted in 32MB zone. It is more complex for ROM, but boot ROM isn't really important to emulate.
-You can get current BASEBLOCK of the PC with the macro

-PC_GETBLOCK(pc)

-There is also an hardware lut. It cheaply converts a virtual address to the physical address (static TLB)
 All those blocks are managed by the BaseBlocks class.
