Image processing and codec capability for video products

Image processing and codec capability for video products

The TXW828 series supports H.264 encoding and decoding up to 1920×1080@30fps, as well as MJPEG codec capability. The ISP supports up to 1920×1080@30fps with dual-channel time-division reuse, 3A, 2D/3D noise reduction, bad pixel correction, lens shading correction, image enhancement, and motion detection for camera, IPC, doorbell, and smart-lock video capture and transmission scenarios.

Dual-core RISC architecture for control and media workloads

The chip integrates one XuanTie E804FD processor and one XuanTie E804D processor with a maximum frequency of 240 MHz. It supports a RISC architecture, 32-bit data, mixed 16/32-bit instructions, DSP instructions, a single-cycle hardware multiplier, and vector interrupt control. CPU0 also supports single-precision floating-point operations, making the platform suitable for wireless protocol, audio-video, peripheral control, and system scheduling tasks.
