The LEON3MP-Nuhorizons design is provided together with GRLIB, and is

<small><span style="font-family: helvetica,arial,sans-serif;">The
|
| 65 |
|
|
LEON3MP is made up by cores from the GRLIB IP library, which are
|
| 66 |
|
|
connected together via the AMBA AHB and APB buses. The plug&play
|
| 67 |
|
|
configuration method of GRLIB makes it possible to assign any
|
| 68 |
|
|
combination of addresses and interrupts to the cores. However, to be
|
| 69 |
|
|
software compatible with simple operating systems such as the LEON
|
| 70 |
|
|
Bare-C cross-compiler, some of the vital cores must be assigned to
|
| 71 |
|
|
predefined addresses and interrupts. The table below shows the
|
| 72 |
|
|
reference assigment in the LEON3MP design:<br>

|
|
design is pre-configured in a suitable manner for the Nuhorizons board.
|
| 243 |
|
|
A special 16-prom controller (nuhosp3.vhd) is used to access the 16-bit
|
| 244 |
|
|
flash, and can be extended to access other on-board units. The sdram
|
| 245 |
|
|
controller uses an inverted clock because the board has no clock
|
| 246 |
|
|
feed-back to phase-ajust the sdram clock. This limits the frequency to
|
| 247 |
|
|
about 40 MHz, and the 50 MHz board oscillator is multiplied with 4/5 by
|
| 248 |
|
|
an on-chip DCM to generate this frequency.</span></small><br style="font-family: helvetica,arial,sans-serif;">

The LEON3MP test bench includes memory models of both boot-prom, sram
|
| 582 |
|
|
and sdram. To build memory images for these models, do 'make soft' .
|
| 583 |
|
|
Note: this will require that the bare-C compiler for LEON3 is
|
| 584 |
|
|
installed,
|
| 585 |
|
|
and /opt/sparc-elf/bin is added to the PATH.<br>
