Samsung Galaxy gets quad core Cortex-A9

Samsung has put four ARM Cortex-A9 processors on a single chip for tablets and phones, including its latest Galaxy, due to appear in May.

Called ‘Exynos 4 Quad’, it is built on the firm’s 32nm high-k metal gate process, allowing each core to run at 1.4GHz.

“Exynos 4 Quad allows system-level architects to integrate power efficiencies into smartphones and tablets which enables double the processing power at a 20% lower power bill over its predecessor, the 45nm Exynos 4 Dual,” said Samsung - for some reason not comparing it with 32nm Exynos 4 Dual with which the Quad is pin-compatible.

Hot-plug functionality supports on-off switching for each core to save power, as does per-core dynamic voltage and frequency scaling.

Applications are also expected in 3D games, video editing, and calculation-intensive simulation.

On-die is a 30frame/s 1080p video engine for recording and play-back, an embedded image signal processor interface for camera use, and an HDMI 1.4 interface to send multimedia content.

A companion power management chip, the S5M8767, includes nine programmable buck converters and 28 LDOs within a 5x5x0.4mm package. Output voltage can be scaled dynamically in 6.25mV steps.

Already in production, samples are with other handset makers.

With a multicore processor, for example, streaming video can run on one core while the other cores simultaneously update applications, connect to the web and scan for viruses.

The package is 12x12x1.37mm.
