ID809 fingerprint chip

ID809 fingerprint chip adopts 168MHz high-performance ARM Cortex-M4 core, which provides a complete DSP instruction set and dedicated floating-point unit (FPU) to directly support complex operations such as trigonometry, filtering, and convolution to speed up fingerprint algorithm execution. The kernel accesses flash memory at high speed with zero wait time, and operates at a high main frequency with a performance of up to 210 DMIPS and a score of up to 565 in CoreMark test. The enhanced power supports the whole process of fingerprint recognition operations, including fingerprint image preprocessing, segmentation and splicing, data feature extraction, feature matching, cross-comparison, identification and unlocking and a series of other commands, which significantly improves the efficiency of fingerprint enrolment and matching. The chip is also equipped with 1MB of high-capacity internal flash and up to 128KB of SRAM, which can support multiple fingerprint information storage and dynamic allocation of memory and other resource overheads of the identification process.
