Это все хорошо...
That all is quite good, but what about second theme???? I can explain it more carefully... Some kind of a program, starting after second boot loader, has a lot of parametres, (We don't any memory manager) which must be avalible at every moment of time... It may be struct or smth like that... so using a stack is a problem... We start this program, and write some parametres after this program at our memory, [program],[free memory........ after starting program [program],[param1],[param2],[paramN],[free memory.... during working of program [program],[free memory],[paramN],[free memory... How can I recieve address of free memory?? I don't know how many params would be in program, before it starts... this is a problem... I know solution using a register or some variable to storage address of free memory, and change it during program... But this works slowly, and we loss some free memory... If somebody have another solution please reply... thx... |
