Moving on to other IP blocks we have concrete information on, we see the Cortex A57 big CPU cluster positioned in one corner of the SoC, largely opposite of the GPU.
This is a hardware cryptographic accelerator that has been part of Exynos SoCs since the S5PC110 (Later renamed Exynos 3110) and is able to accelerate encryption and decryption for various ciphers.
Blandly named Exynos Memory Compressor or M-Comp this is an interesting specialized piece of IP that has yet to play a role in the Galaxy.
Again, we have the obvious two CPU clusters each occupying a port on the CCI which is required for heterogeneous and simultaneous operation system of the two clusters.The per-port bandwidth is limited.5GB/s in read and write directions for a concurrent total of 17GB/s, a figure well be able to correctly verify later on in the CPU performance section.PR material provided by companies often just include rough simplifications such as super diaper baby 2 ebook CPU core counts or GPU configurations.Samsung had implemented this in its Galaxy devices as far back as Android.1.Software Support: MP3, windows Media Audio 9 / 10Pro.Zero overhead looping, audio-optimized DMA unit, configurable single-cycle instruction closely coupled memory (iccm 1KB - 512KB.The Galaxy S6 makes use of a more advanced implementation called zswap which is able to compress memory pages before they need to get swapped out to a swap device, so its a more optimized mechanism that sits closer to the kernels memory management core.Blocks such as the GPU, CPUs and memory controllers can be considered to be representative of their actual size and location, other blocks such as the ISP and the top right quadrant are large functional simplifications for the purpose of presentation.The overall block contains two dedicated hardware fixed-function image scalers as well as a jpeg compression and decompression unit. .Caches closely coupled (single-cycle) memories 16-/32-bit Instruction Set Architecture for the smallest code size.The individual shader cores are among one of the largest individual blocks on the SoC as they come in.75mm.
The G2D block is part of a larger block dedicated to 2D image manipulation called the mscl which is an acronym for M-Scaler although Im not too sure what the M stands for, maybe Media?

We unfortunately won't know for sure until Samsung eventually releases more information on the Exynos 7420.
Altera, aPEX 20KC, aPEX 20KE, aPEX II, arria.Synopsys' DesignWare ARC Sound 211SFX configurable core is a full-featured, mid-range embedded core with best-in-class speed, die area and power characteristics.Kthread_worker_fn0x170/0x170 .It is designed as a complete core solution for system-on-chips (SoCs) targeted at consumer, networking, automotive and other cost-sensitive markets.The last CCI port which I didnt actually depict in the layout should go to the CoreSight block, ARMs system IP for debugging and trace of SoCs.
