ESWIN EIC7700X quad-core RISC-V SoC embeds 19.95 TOPS NPU for Edge AI vision applications

ESWIN EIC7700X block diagram

Yesterday we noted Sipeed was working on the LM5A system-on-module powered by ESWIN EIC7700X quad-core RISC-V processor with a ~20 TOPS AI accelerator in order to integrate it into its Lichee Book laptop and other carrier boards. So today, I’ve decided to look into the EIC7700X SoC designed by “BEIJING ESWIN COMPUTING TECHNOLOGY CO., LTD”, or ESWIN for shorts. The EIC770X features four 64-bit RISC-V (RV64GC) cores clocked up to 1.8 GHz, unnamed 3D and 2D GPUs, a 19.95 TOPS NPU, H.265/H.264 video encoder/decoder capable of handling up to 32x 1080p30 videos, various video output (HDMI + DSI) and input interfaces, dual GbE, 4-lane PCIe Gen 3, and more.   ESWIN EIC7700X specifications: CPU 4x SiFive Performance P550 RV64GC RISC-V cores @ 1.4GHz (up to 1.8GHz) with Cortex-A75-class performance 32KB(I) + 32KB(D) L1 Cache 256KB L2 Cache 4MB shared L3 Cache Cache supports ECC (support SECDED) DNN Accelerator – 19.95 […]

SiFive announces Intelligence X390 NPU, Performance P870 RISC-V core

SiFive Performance P870 RISC V Intelligence X390 NPU

SiFive has announced two new high-performance IP blocks with the Intelligence X390 NPU and the Performance P870 RISC-V core that should find their way into SoC designed for Generative AI and ML applications. We had already covered the Performance P870 and its automotive sibling – the P870-A – from information in an earlier presentation, but the SiFive Intelligence X390 NPU is new to me and appears to be aimed at generative AI in data centers, although we will very soon be seeing companies implement generative AI at the edge in pretty powerful embedded devices. SiFive Performance P870 highlights: Full support for the RVA23 RISC-V profile specification and Vector 1.0 and Vector Crypto Six-wide, out-of-order 64-bit core Up to a 32-core cluster >12 SpecINT2k6/GHz, or a 50% peak single thread performance upgrade over the previous generation SiFive Performance P670 SiFive Features 2x 128b VLEN RVV Vector crypto and hypervisor extensions IOMMU […]

SiFive unveils P870 high-performance core, discusses future of RISC-V

SiFive Hot Chips 2023 x86 vs Arm vs RISC-V

SiFive has just given a presentation at Hot Chips 2023 introducing the new high-performance P870 RISC-V core and its automotive equivalent the P870-A core, plus discussing RISC-V in general, its previous generation RISC-V cores, and what to expect going forward. SiFive has not officially announced the P870 and P870-A cores just yet, so most of the information we have from the English-speaking Internet is from ServeTheHome who managed to get some presentation slides, but this is also corroborated by various Chinese sources on Baidu and Guokr. SiFive P870 and P870-A The P870 and P870-A RISC-V cores are new cores from the SiFive Performance family compatible with the RISC-V RVA23 profile and succeeding the SiFive P670 core. The SpecINT2k6 benchmark reports 17 points per GHz on the P870 compared to 13.2 points per GHz for the P670 (comparable to the Arm Cortex-A78) or about a 29% higher performance at the same […]
