Gk7102 Datasheet Here
The GK7102 SoC was designed for, and continues to be used in, several embedded video applications:
Digitally fuses multiple exposure values to extract details in high-contrast scenes (e.g., a camera pointing toward a bright window).
Note: While some software apps claim 1080p interpolation, the native encoding resolution sweet spot for steady, artifact-free execution is . Connectivity and Peripheral Interfaces

The chip is manufactured by , a company founded in 2008 and headquartered in Changsha, China. The company has received investment from the National Integrated Circuit Industry Investment Fund and has been involved in national science and technology projects. Goke has developed a range of products in fields including secure storage, smart set-top boxes, video encoding/decoding, and IoT, with security chips like the GK7102 as notable products.
The GK7102 is designed as a high-performance, low-power solution for 960p/720p IP cameras. At its heart is an ARM1176 core running at 600MHz, manufactured on a 40nm process. This core is supported by 16KB each of I-Cache and D-Cache. The GK7102 SoC was designed for, and continues
: Hardware-level Auto-Exposure (AE), Auto-White Balance (AWB), and Auto-Focus (AF) engines maximize picture clarity under fluctuating lighting conditions.
Developing for the GK7102 typically involves using GOKE's Software Development Kit (SDK). The chip supports two primary operating systems:
The silicon supports up to . This enables devices to broadcast a high-resolution feed for network video recorders (NVRs) while pushing a low-bandwidth mobile stream and generating continuous snapshot buffers.

Integrated Ethernet PHY and support for external Wi-Fi modules like the MediaTek MT7601 BGA228 (11mm x 11mm) manufactured on a 40nm process. Unifore Security Hardware Variations
At the heart of the GK7102 datasheet is an clocked at 600 MHz . It features separated 16KB Instruction and 16KB Data caches. While legacy compared to modern Cortex-A processors, the ARM11 architecture provides more than enough computing power to run lightweight embedded Linux distributions alongside basic security software stacks, P2P network streaming applications, and motion-detection routines. 2. Multi-Chip Package (MCP) Memory Integration
The GK7102 isn't just an encoder; it includes a sophisticated ISP pipeline designed to enhance image quality in varied lighting conditions.
According to the datasheet, the GK7102 operates at during H.264 1080p encoding. In low-power standby mode, it drops to ~100µA . This makes it a perfect candidate for solar-powered wildlife cameras or doorbell cameras.
