Esperanto implements a new product of 1000 multi-core RISC-V processors.

December 11, 2020


For x86 processors, the open source RISC-V processor is becoming more and more threatening. Not only can it achieve ultra-high frequencies of 5GHz, but now multi-core parallelism is also out of x86. Esperanto has achieved more than 1,000 core RISC-V. processor.

The RISC-V summit will be held on December 8-10. In the past few days, many companies have announced their new products based on the RISC-V instruction set, such as the hard disk master chip released by Seagate.


Esperanto is a start-up company. They will launch a self-developed ET-SoC-1 processor at this summit, mainly for large-scale machine learning applications.

This processor integrates more than 1,000 RISC-V cores with only a single chip. There are two types of 64-bit general-purpose cores inside. One is called ET-Maxion. It was demonstrated at the 2018 RISC-V summit. A high-performance core that uses a superscalar out-of-order execution core design.

There is also a core called ET-Minion, which is a low-power core. It uses a streamlined, sequential execution multi-threaded core, and integrates a large number of vector/tensor co-processing units to accelerate machine learning.

In addition to the advanced core architecture, the ET-SoC-1 processor also supports various software stacks, RISC-V neural network compiler, and industry-standard frameworks, such as PyTorch, ONNX and Glow. The interfaces are also standard. PCIe bus, compatible with existing systems.

According to Esperanto, the ET-SoC-1 processor can provide multiple times the performance of x86, GPU, and FPGA solutions, making the performance density of the data center reach an unprecedented level.

However, they did not provide specific performance and power consumption levels, which should be disclosed at the RISC-V summit.
