B.1 About the differences between the ARM1136JF-S and ARM1176JZF-S
processors
The ARM11 family of high performance processors implements the ARMv6 architecture and
includes the ARM1136JF-S and ARM1176JZF-S processors. These have:
•an integer core
• a level one memory system that comprises caches, write buffers, TCM, and MMU
• level two interfaces
• integrated VFP units
• high performance coprocessor interfaces
• debug and trace support.
The ARM1176JZF-S processor adds:
• the TrustZone architecture for enhanced OS security
• level two interfaces that use AXI busses compatible with AMBA 3.0
• support for IEM for improved low power operation
• support for ARMv6k extensions.
For details of the behavior of the ARM1136JF-S processor, see the ARM1136 Technical
Reference Manual.
