Product Overview
The Q20 chip takes Homsh Technology’s PhaseIrisTM 2nd-generation iris hard-core engine technology as its core,
providing a single-chip solution for iris recognition and matching
applications. It integrates advanced iris processing capabilities
into a single chip, suitable for scenarios such as access control,
smart locks, and iris collectors.
Performance Features
1. Core Acceleration Technology: Adopts PhaseIris Gen2 iris
hard-core acceleration technology to achieve efficient iris data
processing.
2. Interface Support:
Provides GPIO/IIC/Master FIFO interfaces externally.
Master FIFO Interface Compatibility: Supports FT2232/FT600;
supports external bridge USB controllers (such as USB68013,
USB3014/2014); supports external MCU/ARM controllers; maximum
frequency of Master FIFO interface: 100MHz.
3. Camera and ISP Integration:
Supports 2 parallel-port camera inputs, with a maximum support of 5
million pixels.
Integrates ISP, supporting functions such as automatic exposure,
channel balance, and image cropping.
4. High-Speed Matching Performance:
QSPI Flash read template matching: Up to 1,000 templates/s.
When an external USB2.0 interface is connected: Supports real-time
transmission template matching, up to 2,000 templates/s.
When an external USB3.0 interface is connected: Supports real-time
transmission template matching, up to 10,000 templates/s.
Application Fields
● Access Control Systems: Suitable for access control in office
buildings, data centers, high-security areas, etc.
● Smart Devices: Can be applied to smart locks, smart safes, smart
storage cabinets to achieve iris-based identity verification.
● Iris Collectors: As the core component of iris image collection
devices, it supports efficient iris data collection and preliminary
processing.
Why Choose Q20?
1. Hard-Core Engine Advantage: PhaseIris Gen2 hard-core
acceleration technology ensures efficient and stable iris
processing performance.
2. Rich Interface Compatibility: Diverse interfaces
(GPIO/IIC/Master FIFO/USB) support flexible integration with
various peripheral devices and controllers.
3. Scalable Matching Performance: Multi-level matching speeds (QSPI
Flash/USB2.0/USB3.0) adapt to the needs of different scenarios.
4. Integrated ISP Capability: Built-in ISP simplifies camera
integration and image preprocessing, reducing system design
complexity.
