Description
Single transfer
Four-word incrementing burst
Eight-word incrementing burst
Eight-word wrapping burst
All instructions fetches, regardless of the state of ARM9EJ-S core, are made as 32-bit accesses
on the AHB. If the ARM9EJ-S is in Thumb state, then two instructions can be fetched at a time.
The ARM926EJ-S BIU performs address alignment checking and aligns AHB addresses to the
necessary boundary. 16-bit accesses are aligned to halfword boundaries, and 32-bit accesses
are aligned to word boundaries.
Single transfer of word, half word, or byte:
Half-line cache write-back, Instruction prefetch, if enabled. Four-word burst NCNB,
NCB, WT, or WB write.
Full-line cache write-back, eight-word burst NCNB, NCB, WT, or WB write.
Cache linefill
• data write (NCNB, NCB, WT, or WB that has missed in DCache)
• data read (NCNB or NCB)
• NC instruction fetch (prefetched and non-prefetched)
• page table walk read
