MCIMX31/MCIMX31L Technical Data, Rev. 4.3
Freescale Semiconductor
5
Instruction and data memory management units (MMUs), managed using micro TLB structures
backed by a unified main TLB
Instruction and data L1 caches, including a non-blocking data cache with Hit-Under-Miss
Virtually indexed/physically addressed L1 caches
64-bit interface to both L1 caches
Write buffer (bypassable)
High-speed Advanced Micro Bus Architecture (AMBA) L2 interface
Vector Floating Point co-processor (VFP) for 3D graphics and other floating-point applications
hardware acceleration
ETM and JTAG-based debug support
2.1.1
Memory System
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.
Table 2 shows information about the MCIMX31 core in tabular form.

ARM11 or
ARM1136
Platform
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.
