Last Wednesday, Samsung Electronics launched the new Exynos 4 that will allow tablets and smartphones to perform better and use lesser power. According to Samsung, the system-on-chip Exynos 4 has four cores of the ARM Cortex-A9 that will be featured in the much-expected Galaxy S3 and next tablets manufactured by Samsung. Because of the four-core processor, users can multitask much better than single or two-core processors.
According to Taehoon Kim, Samsung's system LSI marketing VP at the department for device solutions, the single battery powers the four cores so efficiency and power management are crucial for mobile gadgets. Samsung's system-on-chip Exynos 4 features four ARM Cortex- A9 cores and runs on 1.40 GHz, which allows switching from one core to another and also for every core dynamic voltage and frequency scaling (DVFS). There is lesser power consumption because of DVFS through adjustment of frequency and voltage that will suit certain workload.
Exynos 4 includes a 30fps HD video hardware codec engine that can record videos at 1080p resolution and interface for an embedded image signal processor and HDMI 1.4. Since the Samsung Galaxy S3 will feature the Exynos 4 A9 quad-core processor system-on-chip instead of the Exynos 5 A15 dual-core processor, this might mean Samsung is anticipating that programs for Android-based devices will depend on multiple-threading and make use of system-on-chips with multiple cores.
Based on claims by Samsung, the Exynos 4 quad-core processor has 32nm process technology that allows efficient and lower power consumption. Moreover, it uses 20 percent lesser energy than its dual-core version, which has a 45nm process technology. Exynos 4 dual will be available at 32nm process technology in the near future.The chip is currently in the process of production and the upcoming Samsung Galaxy S3 will be the first to feature the system-on-chip. The Galaxy S3 is expected to have a May release date.
