Instead of using core migration or the Heterogeneous Multi-Processing (HMP) big.LITTLE models, the 5410 instead used cluster migration which meant either all 4 ARM Cortex A15s or 4 ARM Cortex A7s.

In big.LITTLE Cluster Migration only one of the CPU clusters is active at a time. Since the energy efficiency of the Cortex-A7 is better than the Cortex-A15, high performance applications can be executed on the Cortex-A15 cluster and medium and low performance applications can be executed on the Cortex-A7.Once the Cortex-A7 cluster has reached.

Figure 1 shows a reference big.LITTLE processor design[2]. In the processor, there are two clusters: a big cluster and a little cluster. In the big cluster, there are two big cores (CortexA-57), and 2MB of shared L2 cache. In the little cluster, there are four little cores (CortexA-53), and 1MB of shared L2 cache. Figure 1 also shows the CCI.

Slide 2 TC2 - ARM's big.LITTLE implementation Has a cluster of Cortex-A15 processors (big) and a cluster of Cortex-A7 processors (LITTLE) in the same system. Cortex-A7 and A15 are architecturally similar - ARM v7A. Processor caches are kept coherent using a cache coherent interconnect (CCI-400 on TC2).

Throughput increases as we add more Big cores but drops sharply on the addition of Small cores from another cluster for HMP. Inter-cluster communication overhead involved in the use of HMP explains the drop. No HMP configuration surpasses the performance of configuration with four Big cores. Therefore, Figure 3 empirically shows that we.

TLDR. This work uses reinforcement learning to map pairs formed by a program phase and a hardware state to the configuration that best fit this setup, and provides evidence that Astro, the Astro system, outperforms GTS, the ARM-based Linux scheduler tailored for heterogeneous architectures, on the parallel benchmarks from Rodinia and Parsec. 6.

using the HMP mode to simultaneously run on the big and LITTLE clusters (i.e., A7/A15 in the gure), the execution time is usually slower to that of the big cluster alone, despite using four additional actives cores. An even higher penalty is observed when operating the LITTLE cluster at a lower frequency, especially so for the lud, nn and nw.

2. As far as I know, big cores and little cores are in separate clusters on big.LITTLE system. And cache coherence between clusters requires the regions are marked as Outer Shareable and is very expensive. I have checked the Linux kernel code, and seems it only requires coherence in Inner Shareable domain.

ARM big.LITTLE is a heterogeneous computing architecture developed by ARM Holdings, coupling relatively battery-saving and slower processor cores ( LITTLE) with relatively more powerful and power-hungry ones ( big ). The intention is to create a multi-core processor that can adjust better to dynamic computing needs and use less power than clock.
