Detailed Description

Implements a memory map between physical and virtual codeplug addresses.

The addresses, the codeplug is encoded in, are virtual. These codeplug blocks are then written to different physical addresses.

Member Function Documentation

uint32_t DM32UV::AddressMap::toPhysical ( uint32_t virt ) const

Maps the given virtual codeplug address to a physical memory address.

If virtual address is unknown – that is, not mapped – std::numeric_limits<uint32_t>::max() gets returned.

uint32_t DM32UV::AddressMap::toVirtual ( uint32_t phys ) const

Maps the given physical address to a virtual codeplug address.

If physical address is unknown – that is, not mapped – std::numeric_limits<uint32_t>::max() gets returned.

QMap<uint32_t, uint32_t> DM32UV::AddressMap::_toPhysical

protected

Holds only the prefix address mapping from virtual to physical addresses.

That is addr>>12.

QMap<uint32_t, uint32_t> DM32UV::AddressMap::_toVirtual

protected

Holds only the prefix address mapping from physical to virtual addresses.

That is addr>>12.
