摘要

The ET-SoC-1 has over a thousand RISC-V processors on a single TSMC 7nm chip, including: • 1088 energy-efficient ET-Minion 64-bit RISC-V in-order cores each with a vector/tensor unit • 4 high-performance ET-Maxion 64-bit RISC-V out-of-order cores • >160 million bytes of on-chip SRAM • Interfaces for large external memory with low-power LPDDR4x DRAM and eMMC FLASH • PCIe x8 Gen4 and other common...
