Socionext SC2A11 Low Power Server Processor Comes with 24 Cortex-A53 Cores, Scales up to 1536 Cores via PCIe
Socionext SC2A11 is an 24-core (tetracosa) ARM Cortex-A53 processor designed for low-power server system suitable for edge computing, web server & indexing, cloud computing, and any applications that do not require high single thread peak performance. The company also designed SC2A20 switch SoC that allows up to 64 SC2A11 processors (1536 cores) to communicate over PCI Express using Socionext DDT (Direct Data Transaction).
- Processor – 24x ARM Cortex-A53 MPCore cores @ up to 1GHz, with 32KB/32KB I/D L1 cache, 256 KB L2 cache, and 4MB L3 cache
- Memory I/F – DDR4-2133Mbps 64-bit + ECC
- Flash I/F – HSSPI, eMMC
- PCIe – PCI Express Gen2, Root/Endpoint select, 4 lanes (2 systems/ for SoC IF)
- LAN – 2x 1Gbps with IPSec Network Offload Engine (wire-speed)
- Serial I/F – UART, I2C, GPIO
The company did not provide any info about software, but it’s safe to assume it’s running Linux. There’s some code on the Linux mailing list for other Socionext processor, but nothing for SC2A11. Another interesting use case is to connect several processor element card (PEC) based on SC2A11 using SC2A20 switch SoC, and a few Socionext MB86M30 ASSP via PCIe to encoding raw videos to 4K HEVC / H.265 videos @ 60 fps.
Socionext was at Linaro Connect Budapest 2017 demonstrating some of those PECs, and Charbax checked them out at the demo event, where they showcase the boards, and explained a little about them, and their relation with Linaro (as a member).
You won’t find than many details on Socionext SC2A11 product page, but at least you can inquire the company if you need more information.
