Figure 4–3. Local Reference Design
Note to Figure 4–3 :
(1) The DMA Engine, lm_lastn and local master blocks are not applicable for the pci_t32 and pci_t64 local reference
designs.
Table 4–8 shows the memory map of the Altera PCI MegaCore function
required to use the local reference design.
The reference design has the following elements:
■ Local target
■ DMA engine
■ Local master
■ lm_lastn generator
■ Prefetch
■ LPM RAM

Memory Region Mapping Block size Address Offset Description
BAR0 Memory Mapped 1 KByte 000-3FF Maps the LPM_RAM function.
BAR1 I/O Mapped 16 Bytes 0-F Maps the I/O register.
BAR2 Memory Mapped 1 KByte 000-3FF Maps the trg_termination register and
DMA engine registers. Only the lower 24
Bytes of the address space are used.
