Description:

AI is pervasive today, from consumer to enterprise applications. With the explosive growth of connected devices, combined with a demand for privacy/confidentiality, low latency and bandwidth constraints, AI models trained in the cloud increasingly need to be run at the edge.

MAIX is Sipeed’s purpose-built module designed to run AI at the edge, we called it AIoT. It delivers high performance in a small physical and power footprint, enabling the deployment of high-accuracy AI at the edge, and the competitive price makes it possible to embed to any IoT devices. As you see, Sipeed MAIX is quite like Google edge TPU, but it acts as the master controller, not an accelerator like edge TPU, so it is more low cost and low power than AP+edge TPU solution.

The MAIX Dock series uses the Kanetech technology AIchip K210As a core unit, with independenceFPUDual core processing,64BitCPUBit width,8MOn-chip SRAM,400MAdjustable nominal frequency, support for double-precision of multiplication, division, and square root operations CPU. High-performance core processing features are exposed.

in AIProcessing aspectK210Convolution, batch normalization, activation, pooling, etc. can be performed. At the same time, the pre-processing of voice direction scanning and voice data output can also be performed.

MAIX Dock has the following capabilities

Digital video interface (DVP)
Universal asynchronous transceiver(UART)
Direct memory access controller(DMAC)
Integrated circuit built-in bus(I2C)
Serial peripheral interface(SPI)
Integrated circuit built-in audio bus(I2S)
Joint Test Working Group(JTAG)
Field programmable IO Array (FPIOA/IOMUX)

MAIX's Advantage and Usage Scenarios:

MAIX is not only hardware but also provides an end-to-end, hardware + software infrastructure for facilitating the deployment of customers' AI-based solutions.
Thanks to its performance, small footprint, low power, and low cost, MAIX enables the broad deployment of high-quality AI at the edge.
MAIX isn't just a hardware solution, it combines custom hardware, open software, and state-of-the-art AI algorithms to provide high-quality, easy to deploy AI solutions for the edge.
MAIX can be used for a growing number of industrial use-cases such as predictive maintenance, anomaly detection, machine vision, robotics, voice recognition, and many more. It can be used in manufacturing, on-premise, healthcare, retail, smart spaces, transportation, etc.
