The plug&play configuration method of GRLIB makes it possible to assign any combination of addresses and interrupts to the cores. However, to be software compatible with simple operating systems such as the LEON Bare-C cross-compiler, some of the vital cores must be assigned to predefined addresses and interrupts. The table below shows the reference assigment in the LEON3MP design:<br> <br> </span></small> <table style="width: 100%; text-align: left;" border="1" cellpadding="2" cellspacing="2"> <tbody> <tr> <th style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">Core</span></small></th> <th style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">Memory area<br> </span></small></th> <th style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">Interrupt</span></small></th> </tr> <tr> <td style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">PROM/SDRAM controller<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">0x00000000 - 0x20000000 : 8 Mbyte 8-bit flash PROM<br> 0x40000000 - 0x80000000 : 64 Mbyte 32-bit SDRAM<br> 0x80000000 - 0x80000100 : Configuration registers (APB)<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">-</span></small></td> </tr> <tr> <td style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">APB bridge<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">0x80000000 - 0x80100000 : APB bus<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">-</span></small></td> </tr> <tr> <td style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">UART</span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">0x80000100 - </span></small><small><span style="font-family: helvetica,arial,sans-serif;">0x80000200 : UART1 registers</span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">2</span></small><br> </td> </tr> <tr> <td style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">Interrupt controller</span></small><br> </td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">0x80000200 - </span></small><small><span style="font-family: helvetica,arial,sans-serif;">0x80000300 : IRQ registers<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">-</span></small></td> </tr> <tr> <td style="vertical-align: top; width: 250px;"><small><span style="font-family: helvetica,arial,sans-serif;">Timer unit<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;"></span></small><small><span style="font-family: helvetica,arial,sans-serif;">0x80000300</span></small><small><span style="font-family: helvetica,arial,sans-serif;"> -</span></small><small><span style="font-family: helvetica,arial,sans-serif;"></span></small><small><span style="font-family: helvetica,arial,sans-serif;"> 0x80000400 : timer registers<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">8, 9<br> </span></small></td> </tr> <tr> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">LEON3 debug support unit (DSU)<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">0x90000000 - 0xA0000000 : DSU registers<br> </span></small></td> <td style="vertical-align: top;"><small><span style="font-family: helvetica,arial,sans-serif;">-</span></small></td> </tr> </tbody> </table> <small><span style="font-family: helvetica,arial,sans-serif;"><br> Additional (optional) IP cores are assigned addresses and interrupts as desribed in the table below.
