Custom Amlogic S928X TV Box Solution

Custom Amlogic S928X TV Box solutions deliver high-performance embedded computing, integrating 8K media processing, AI acceleration, and robust I/O (HDMI 2.1, USB 3.0, Wi-Fi 6). Designed for industrial, automotive, and commercial applications, these systems prioritize scalability and thermal management for sustained edge-AI workloads, with full OEM/ODM customization support.

 1. Core Architecture & Processing  

- CPU: Hybrid 64-bit octa-core design:  

  - 1× ARM Cortex-A76 @ up to 2.4GHz (high-performance core)  

  - 4× ARM Cortex-A55 @ up to 2.0GHz (efficiency cores)  

  - Big.LITTLE architecture for dynamic task allocation (heavy workloads vs. background tasks).  

- Process Node: 12nm FinFET (balance of power efficiency and thermal management).  

- AI Acceleration: Integrated NPU with up to 4 TOPS (Tera Operations Per Second) for on-device AI tasks (e.g., image recognition, voice processing).  

 

 2. Graphics & Video Processing  

- GPU: ARM Mali-G57 MC2 supporting:  

  - OpenGL ES 3.2, Vulkan 1.2, OpenCL 2.0 (GPU compute)  

  - 8K UI rendering at 30fps / 4K@120fps.  

- VPU (Video Processing Unit):  

  - True 8K@60fps decoding: AV1, AVS3, H.265/HEVC, VP9, AVS2  

  - 4K@120fps decoding: H.264, MPEG-4  

  - Low-latency 4K@60fps encoding (H.265/H.264).  

  - HDR support: Dolby Vision, HDR10+, HLG, HDR Vivid.  

 

 3. Memory & Storage Interfaces  

- RAM: Supports up to 8GB LPDDR4/LPDDR4X (64-bit bus, ~40GB/s bandwidth).  

- Storage:  

  - eMMC 5.1 flash (up to 128GB)  

  - External storage via TF/microSD card slot  

  - USB 3.0 for high-speed external drives.

  - USB 3.0 ×1 + USB 2.0 ×1 (OTG support)  

  - USB Type-C (power/data in select designs).  

 5. Development Board-Specific Features  

- Expansion & Debugging:  

  - UART, I²C, SPI, GPIO headers for sensor/peripheral integration  

  - JTAG interface for low-level debugging.  

- Power Management:  

  - 5V/3A DC input (typical for TV boxes)  

  - RTC (Real-Time Clock) for time-sensitive applications.  

- Thermal Design:  

  - Metal chassis (common in boards like X96 X10) for passive cooling  

  - Optional active cooling for sustained 8K workloads.
