Samsung Galaxy gets quad core Cortex-A9
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.
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.Tags: A9, ARM, core, Cortex, Galaxy, quad, Samsung
