2.1.1
The ARM1136JF-S complex includes 16 KB Instruction and 16 KB Data L1 caches. It connects to the
MCIMX31 L2 unified cache through 64-bit instruction (read-only), 64-bit data read/write (bi-directional),
and 64-bit data write interfaces.
The embedded 16K SRAM can be used for audio streaming data to avoid external memory accesses for
the low-power audio playback, for security, or for other applications. There is also a 32-KB ROM for
bootstrap code and other frequently-used code and data.
A ROM patch module provides the ability to patch the internal ROM. It can also initiate an external boot
by overriding the boot reset sequence by a jump to a configurable address.

and JTAG-based debug support
The ARM1136™ Platform consists of the ARM1136JF-S core, the ETM
real-time debug modules, a 6 x 5 multi-layer AHB crossbar switch (MAX), and
a Vector Floating Processor (VFP).
The MCIMX31 provides a high-performance ARM11 microprocessor core and
highly integrated system functions. The ARM Application Processor (AP) and
other subsystems address the needs of the personal, wireless, and portable
product market with integrated peripherals, advanced processor core, and
power management capabilities.
