The AVR32 AP implementation

The first implementation of the AVR32B microarchitecture is designed as an application proces-

sor and called AVR32 AP. This implementation targets high-performance applications in the

DSP, multimedia and wireless segment, and provides:

• Advanced OCD system.

• Efficient data and instruction caches.

• Full MMU.

• Java acceleration is implemented in hardware.

• Fast interrupt handling is provided through shadowed register banks for interrupt priority 3.

• SIMD extension.

• DSP extension.

• Service Access Port (SAP) that gives an external JTAG controller access to memories and

registers inside the AVR32 AP core.
