ST-Ericsson's eQuad technology is a CPU architecture in which each processor core can operate efficiently in two modes: as an industry-leading high performance core, running at up to 2.5 GHz in the case of the NovaThor L8580, or as a very low-power core running at 0.6 V. This is achieved by transistor-level electrical bias switching to allow each of two physical cores to run in two different modes, creating an electrically-enabled quad core.
"At ST-Ericsson we are focused on delivering the best experience for the smartphone users of today. With eQuad we have chosen to innovate where it most benefits the user by making real world applications run significantly faster while at the same time ensuring ultra-low power consumption for devices that run cooler and last longer," said Didier Lamouche, President and CEO of ST-Ericsson. "Building on the architecture of our first generation NovaThor L8540 LTE ModAp announced last year, we believe our new platform represents a real industry breakthrough. It combines the most advanced technologies available, including STMicroelectronics' innovative 28 nm FD-SOI process, to create an unrivalled blend of unsurpassed performance with unequalled power efficiency in an advanced LTE integrated ModAp."
The NovaThor L8580 integrates an eQuad 2.5 GHz processor based on ARM Cortex-A9, a powerful Imagination PowerVR™ SGX544 GPU running at 600 MHz and an advanced multimode LTE modem on a single 28 nm FD-SOI die.
Building on the NovaThor L8540, the NovaThor L8580 highlights the advantages of FD-SOI technology combined with innovative techniques to increase performance and conserve power. For customers, the advantages of the NovaThor L8580 include:
- CPUs that run 35% faster while GPU and multimedia accelerators run 20% faster;
- Cooler operation when delivering high performance, consuming 25% less power than rival architectures; and
- Low power mode can deliver up to 5000 DMIPS at 0.6V - more than enough computing power for the majority of applications in everyday use. This low power mode consumes 50% less
