Cortex A15, or Eagle, is the name of ARM’s next generation microarchitecture. After Cortex A9, Eagle will raise the bar further with up to four physical cores and clock frequencies up to 2.5 GHz. ARM confirms that it is working on a multi-threading technology to follow Cortex A15.

Going for multi-threading in a microarchitecture that already holds four physical cores sends out a clear signal to partners as to where ARM aims to take the architecture. We have already seen how servers have started to gain interest in the energy efficient ARM circuits and with better multi-threading performance it can gain whole new ground there.

Unfortunately ARM is very quiet about when we will see the multi-threading technology on the market, but since the development wasn’t ready for Cortex A15 that is said to launch in 2013, it may take a bit longer than that.
