Since I started to work with embedded systems I had to start thing about pointers... A subject foreign in my previews Java development. Bellow is a small spinet of my code to copy arrays with pointers. Also the use of some Microblaze functions use are shown... void BufferMemoryCopy ( void * dest , GPS_BUFFER * buff , u16 buff_offset , u32 size ) { // Microblaze -- typedef Xuint16 u16; u16 pos = ( buff -> Tail16 + buff_offset ) & GPS_FIFO_MASK ; // Fifo mast is used in roun buffer         if ( ( pos + size ) <= GPS_FIFO_SIZE ) {         memcpy ( dest , & buff -> Buffer [ pos ] , size ) ; } else { memcpy ( dest , & buff -> Buffer [ pos ] , GPS_FIFO_SIZE - pos ) ; memcpy ( dest   + ( GPS_FIFO_SIZE - pos ) , & buff -> Buffer [ 0 ] , size - ( GPS_FIFO_SIZE - pos ) ) ;
