2 Functional Description and Application Information
2.1 ARM926 Microprocessor Core Platform
The ARM926 Platform consists of the ARM926EJ-S processor, ETM9, ETB9, a 6 × 3 Multi-Layer AHB
crossbar switch (MAX), and a “primary AHB” complex.
• The instruction bus (I-AHB) of the ARM926EJ-S processor is connected directly to MAX Master
Port 0.
• The data bus (D-AHB) of the ARM926EJ-S processor is connected directly to MAX Master Port 1.
Four alternate bus master interfaces are connected to MAX Master Ports 2–5. Three slave ports of the
MAX are AHB-Lite compliant buses. Slave Port 0 is designated as the “primary” AHB. The primary AHB
is internal to the platform and has five slaves connected to it: the AITC interrupt module, the MCTL
memory controller, and two AIPI peripheral interface gaskets. Slave Ports 1 and 2 of the MAX are referred
to as “secondary” AHBs. Each of the secondary AHB interfaces is only accessible off platform.
The ARM926EJ-S processor supports the 32-bit and 16-bit ARM Thumb instruction sets, enabling the
user to trade off between high performance and high-code density. The ARM926EJ-S processor includes
features for efficient execution of Java byte codes, providing Java performance similar to the just-in-time
(JIT) compiler—which is a type of Java compiler—but without the associated code overhead.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both
hardware and software debugging. The ARM926EJ-S processor has a Harvard cached architecture and
provides a complete high-performance processor subsystem, including the following:
• An ARM9EJ-S integer core
• A Memory Management Unit (MMU)
• Separate instruction and data AMBA AHB bus interfaces
• ETM and JTAG-based debug support
