- help
- 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.
