SQLite memory requirements depends on how it is compiled and how it is used. You should use experiments to determine how much memory is required for your particular project. If SQLITE_ENABLE_MEMORY_MANAGEMENT is defined when you compile, then the global variable contains the highwater mark of your total heap memory utilization. > > ----- Original Message ----- > From: "Sarah" <[EMAIL PROTECTED]> > To: <sqlite-users@sqlite.org> > Sent: Thursday, July 27, 2006 3:47 PM > Subject: [sqlite] Another question about RAM > > > > Hi, all > > > > I want to build SQLite on the uc/os-II kernel in an embedded device. > > > > Because uc/os-II doesn't provide malloc(), free() to manage memory, instead, > > it divides the memory into fixed-length blocks and provides OSMemGet() and > > OSMemPut() to > > get and put fixed-length memory block. > > > > In order to port SQLite, I have to wrap uc/os-II with a set of standard > > memory management APIs(malloc, free...). > > So I need to decide in advance that which 'fixed length' will be better. > > That is to say, when using malloc() to > > allocate memory in SQLite, how much memory is needed in most cases? what > > does it depend on? > > > > Thanks. > > > >
