Description
Single transfer
Four-word incrementing
burst
Eight-word incrementing
burst
Eight-word wrapping burst
Table 6-1 shows the HBURST encodings that the ARM926EJ-S processor uses, and the
operations that perform each burst size.
Incr4 and Incr8 bursts can be aligned to any word boundary.
The ARM926EJ-S processor performs all Thumb instruction fetches as word-wide
transfers on the AHB. See Mapping of level one and level two (AHB) attributes on
page 6-5.
All burst reads and writes are performed by the ARM926EJ-S processor as word-wide
transfers (HSIZE[2:0] = 010). Single reads and writes are performed as byte
(HSIZE[2:0] = 000), halfword (HSIZE[2:0] = 001), or word wide transfers
(HSIZE[2:0] = 010).

Note
Operation
Single transfer of word, halfword, 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
continuation of a burst that either lost grant or received a
Split/Retry response.
