Functional Description and Application Information
Separate instruction and data AMBA AHB bus interfaces
ETM and JTAG-based debug support
The ARM926EJ-S processor provides support for external coprocessors enabling floating-point or other
application-specific hardware acceleration to be added. The ARM926EJ-S processor implements ARM
architecture version 5TEJ.
The four alternate bus master ports on the ARM926 Platform, which are connected directly to master ports
of the MAX, are designed to support connections to multiple AHB masters external to the platform. An
external arbitration AHB control module is needed if multiple external masters are desired to share an
ARM926 Platform alternate bus master port. However, the alternate bus master ports on the platform
support seamless connection to a single master with no external interface logic required.
A primary AHB MUX (PAHBMUX) module performs address decoding, read data muxing, bus
watchdog, and other miscellaneous functions for the primary AHB within the platform. A clock control
module (CLKCTL) is provided to support a power-conscious design methodology, as well as
implementation of several clock synchronization circuits.
2.1.1
Memory System
The ARM926EJ-S complex includes 16-Kbyte Instruction and 16-Kbyte Data caches. The embedded
45-Kbyte SRAM (VRAM) can be used to avoid external memory accesses or it can be used for
applications. There is also a 24-Kbyte ROM for bootstrap code.

Module Inventory
Table 2 shows an alphabetical listing of the modules in the i.MX27/MX27L multimedia applications
processors. A cross-reference to each module’s section and page number goes directly to a more detailed
module description for additional information.

1-Wire
1-Wire Interface
Connectivity
Peripheral
The 1-Wire module provides bi-directional communication
between the ARM926EJ-S and the Add-Only-Memory EPROM
(DS2502). The 1-Kbit EPROM is used to hold information
about battery and communicates with the ARM926 Platform
using the IP interface.
AIPI
AHB-Lite IP
Interface
Module
Bus Control
The AIPI acts as an interface between the ARM Advanced
High-performance Bus Lite. (AHB-Lite) and lower bandwidth
peripherals that conforms to the IP Bus specification, Rev 2.0.
AITC
ARM9EJ-S
Interrupt
Controller
Bus Control
AITC is connected to the primary AHB as a slave device. It
generates the normal and fast interrupts to the ARM926EJ-S
processor.
ARM926EJS
ARM926EJ-S
CPU
The ARM926EJ-S (ARM926) is a member of the ARM9 family
of general-purpose microprocessors targeted at multi-tasking
applications.
