Samsung's Exynos 5 Octa To Fire All '8 Cores' By Year End

Heterogeneous Multi Processing feature lets the CPU use all eight cores simultaneously.

 

Looks like all the S Lag jokes have finally begun bothering Samsung. After suffering much ridicule for lag on its flagship Galaxy S4 smartphone, the Korean electronics Goliath has finally decided to take a stab at fixing user complaints. The Exynos 5 Octa mobile processors will soon be able to use all eight cores simultaneously. This will be achieved by giving the SOC Heterogeneous Multi-Processing (HMP) capability.

In simple terms, this implementation allows the phone to employ both, the high powered Arm A15 cores as well as the power efficient A7 cores as per the task priority. Processing threads with a higher priority will be handled by the A15, whereas the lower priority ones will be dispatched by the A7 simultaneously—all without waiting for the phone to switch between the two quad-core processing banks. Samsung claims the feature will allow the SOC to be even more efficient than before. The video below should throw more light on the working of this new technology.



The performance hiccups in the Galaxy S4 were attributed to the fact that the SOC couldn't use all eight cores at the same time. The lag was noted when the phone would switch to the more power-efficient (albeit slower) Arm A7 core group instead of the faster Arm A15 cores in order to conserve battery. The HMS implementation, however, will allow the phone the flexibility of using anything from one Arm A7 processor for a simple background update task, or all eight cores for a graphics intensive game.

Although Samsung's press release says that the Exynos Octa CPUs will be able to use all eight cores simultaneously by the end of this year, there's no word on exactly how the HMP feature will be integrated. Whether this will be done through an update or will the feature be found only on new Exynos 5 Octa chips instead is still a mystery.
