2. FX3 CPU Subsystem
The EZ-USB FX3 device has an embedded 32-bit ARM926EJ-S core that delivers a processing capability up to 220 MIPS.
This ARM core is coupled with instruction and data caches, Tightly Coupled Memories (TCM), and a PL192 vectored interrupt
controller (VIC). FX3 also implements the standard ARM JTAG Test Access Point (TAP), which allows you to use standard
JTAG debuggers to debug firmware applications.
The ARM926EJ-S processor is targeted at multitasking applications and can support high-performance and low-power
requirements.
Interrupts in the FX3 device are managed through the standard ARM PL192 VIC block.
2.1 Features
The ARM9 core in the FX3 device supports the following features:
■ Operation at frequencies up to 200 MHz
■ Support for both 32-bit ARM and 16-bit thumb instructions
■ Integrated data and instruction caches of 8 KB each
■ Dedicated instruction and data TCMs for guaranteed low-latency memory access
■ VIC capable of managing 32 internal interrupt sources with programmable interrupt priorities
■ Standard ARM JTAG interface for debugging
■ Clock frequency control for power saving
■ System RAM on FX3 device serves as main storage for code and data
