1. Hardware Architecture and Design
1.1 Compact Physical Structure
The Atlas 200 AI Acceleration Module (Model 3000) adopts a high-density integrated design with physical dimensions of 55mm x 45mm x 4.3mm (standard form), supporting a 6mm thickness expansion through a replaceable connector scheme. The module’s surface features an anodized aluminum heat dissipation shell, with built-in multi-layer graphene thermal pads that improve thermal conductivity efficiency by 40% compared to traditional solutions. The gold finger area is equipped with 132 signal contacts, including 4 pairs of differential clock signal lines and 16 groups of high-speed PCIe channels, meeting industrial-grade seismic resistance standards (10G vibration intensity).
1.2 Key Signal Interface Definitions
The MXM 3.0 interface at the module’s edge defines three categories of core signal groups:
Computing core interface: PCIe 3.0 x4 channels (supports CLKREQ power-saving control), LPDDR4X-2133 memory bus
Extended function interface: RGMII Gigabit Ethernet PHY, USB 3.0 SuperSpeed differential pairs, I2C bus (supports 1MHz clock rate)
System management interface: PMIC_VDD (power management), JTAG debugging port, temperature sensor ADC input
Specially designed ESD protection circuits can maintain normal operation under contact discharge conditions of 8kV, complying with IEC 61000-4-2 standards.
2. Multi-Modal Application Scenario Analysis
2.1 Main Processor Mode
When the module operates in autonomous control mode, its built-in 8-core Cortex-A55 processor cluster can support a complete Linux system. Typical configuration schemes include:
– Mounting 32GB of storage space via the eMMC 5.1 interface
– Directly connecting a network camera (supporting up to 4 channels of 1080P input) via the RGMII interface
– Driving an OLED status display via the SPI bus
In this mode, developers can directly deploy lightweight AI inference services on the module, such as implementing a facial recognition payment system in smart retail cabinets, with measured end-to-end processing latency of less than 300ms.
2.2 Co-Processor Mode
In this mode, the module acts as a peripheral expansion unit, interacting with the main CPU through GPIO_12 (wake signal) and GPIO_15 (status indication). Typical application features include:
– The main control side sends control commands via the I2C bus (standard SMBus protocol)
– Using zero-copy DMA mechanisms to transfer video stream data
– Supporting dynamic voltage frequency scaling (DVFS), with idle power consumption reduced to 0.5W
In drone obstacle avoidance systems, this mode can achieve real-time environmental perception calculations within a 200ms cycle, improving energy efficiency by 8 times compared to pure CPU solutions.
2.3 PCIe Slave Device Mode
As a PCIe endpoint device, the module needs to be deeply integrated with the host system:
– The hardware layer must ensure REFCLK± clock jitter is less than 1ps RMS
– The driver layer implements MSI-X interrupt service routine registration
– The application layer calls AI computing power through the OpenCL 2.0 interface
Data from a smart traffic project shows that, in conjunction with a Xeon E3 host, a single module can simultaneously process 16 channels of video structured analysis, achieving a target detection accuracy of up to 99.2%.
3. Core Performance and Technical Breakthroughs

The chip uses TSMC’s 12nm FinFET process and integrates two major innovative architectures:
Da Vinci computing core: Each AI Core contains 3 cubic computing units, supporting FP16/INT8 mixed precision operations
Intelligent data routing: Achieves 96GB/s on-chip data throughput through the NOC on-chip network
In natural language processing tasks, the BERT-base model inference speed can reach 450 sentences/second, improving by 2.3 times compared to similar products.
3.2 Video Processing Capabilities
The module is equipped with a dedicated video processing unit (VPU), supporting:
– Multi-channel video parallel decoding (H.265 [email protected])
– Dynamic resolution scaling (real-time conversion from 4K to 1080P)
– Intelligent bitstream control (CBR/VBR dual mode)
In video conferencing scenarios, it can achieve real-time background blurring processing for 16 channels of 1080P video, reducing GPU resource occupancy by 70%.
4. Engineering Deployment and Maintenance Guidelines
4.1 Hardware Installation Specifications
– Mechanical fixation: It is recommended to use M2.5 stainless steel screws, with a locking torque of 0.4N·m ±10%
