MMU starting from version 3 (found in ARC 770) and now
|
|
|
|
|
version 4 (found in ARC HS38) allows the selection of the
|
|
|
|
|
page size during ASIC design creation.
|
|
|
|
|
|
|
|
|
|
The following options are available for MMU v3 and v4: 4kB,
|
|
|
|
|
8kB and 16 kB.
|
|
|
|
|
|
|
|
|
|
The default is 8 kB (that really matches the only page size
|
|
|
|
|
in MMU v2). It is important to build a toolchain with page
|
|
|
|
|
size matching the hardware configuration. Otherwise
|
|
|
|
|
user-space applications will fail at runtime.
