Samsung Exynos 5 Octa CPU to have use of all 8 cores at one time starting in Q4
When MediaTek introduced the world's first true octa-core chip in July, that put pressure on Korean OEM Samsung. After all, the Samsung Exynos 5 Octa can only use one set of four cores at a time while the MT8135 can use all eight cores at a time. But thanks to the Heterogeneous Multi-Processing solution, the Samsung chip will also be able to use all eight cores at once, starting in the fourth quarter.
The setup allows big heavy duty tasks to run on the "big" A15 cores and small housekeeping chores can run on the "LITTLE" A7 cores without having to switch back and forth as currently required. Sammy's presser points out that being able to access all eight cores at once will improve 3D gaming, Augmented Reality, and advanced web browsing.
Samsung didn't say that we would see these chips in any current smartphone model, but it is a good bet that the Samsung Galaxy S5 will implement the silicon in at least some regions.

"It's usually assumed that the big CPU will do all the performance-critical work, however, power-efficient little cores can handle many significant workloads all on their own, so the workload is balanced within the system. big.LITTLE processing is designed to deliver the right combination of processors for a specific job. An eight-core processor with HMP is the truest form of the big.LITTLE technology with limitless benefits to the users of high-performance, low-power mobile products."-Taehoon Kim, vice president, System LSI marketing, Samsung Electronics

Seoul, Korea, September 10, 2013
Samsung Electronics Co., Ltd., a world leader in advanced semiconductor solutions, today announced its Heterogeneous Multi-Processing (HMP) solution for the Exynos 5 Octa to fully maximize the benefits of the ARM® big.LITTLE™ technology. The HMP capability gives system-level designers the ability to develop solutions that deliver the right combination of high-performance and low-power to carry out tasks such as 3D gaming, complex augmented reality and advanced web browsing.
"It's usually assumed that the big CPU will do all the performance-critical work, however, power-efficient little cores can handle many significant workloads all on their own, so the workload is balanced within the system," said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. "big.LITTLE processing is designed to deliver the right combination of processors for a specific job. An eight-core processor with HMP is the truest form of the big.LITTLE technology with limitless benefits to the users of high-performance, low-power mobile products."
"ARM big.LITTLE multi-processing technology delivers the highest performance and efficiency across the widest range of workloads," said Noel Hurley, vice president, Strategy and Marketing, Processor Division, ARM. "We welcome Samsung's continued commitment to deploying the leading-edge technology on their latest chips featuring the ARM Cortex™-A series of processors, ARM Mali™ GPUs and ARM Artisan™ physical IP."
HMP is the most powerful use model for ARM big.LITTLE technology, as it enables the use of all physical cores at the same time. Software threads with high priority or high computational intensity can be allocated to the 'big' Cortex-A15 cores while threads with less priority or are less computationally intensive, can be performed by the 'LITTLE' Cortex-A7 cores, enabling a highly responsive, low-energy system to be built.
Software implementation is essential to maximizing the benefits of big.LITTLE technology. Multi-processing software controls the scheduling of threads of execution to the appropriate core. In earlier versions of the big.LITTLE software, the whole processor context is moved up to the 'big' core or down to the 'LITTLE' core based on the measured work load. In-depth study and analysis of diverse use case scenarios enable Samsung to achieve efficiency and high-performance, while managing power levels to deliver optimal user environments.
The HMP solution for Samsung's Exynos 5 Octa application processors will be available to customers in 4Q of 2013.
