ARM11

The implementation included a significantly improved instruction processing pipeline, compared to previous ARM9 or ARM10 families, and is used in smartphones from Apple, Nokia, and others.

It incorporates all ARM926EJ-S features[citation needed] and adds the ARMv6 instructions for media support (SIMD) and accelerating IRQ response.

Microarchitecture improvements in ARM11 cores[4] include: JTAG debug support (for halting, stepping, breakpoints, and watchpoints) was simplified.

Without such attention, integrating an ARM11 with third-party designs could risk exposing hard-to-find latent bugs.

Due to ARM cores being integrated into many different designs, using a variety of logic synthesis tools and chip manufacturing processes, the impact of its register-transfer level (RTL) quality is magnified many times.
