WT8932
The WT8932 is a high performance image processor which incorporates a 32-bit RISC CPU with DSP instruction set that operates up to 180 MHz and optimized for image sensors with HiSPi/MIPI interfaces. In addition, the WT8932 embeds a hardware image processor unit (IPU) and supports input resolution up to 8 megapixels, providing real-time and superior visibility technology for camera applications. The WT8932 requires few external components and can be easily be integrated into a camera module. It thus simplifies the system hardware design and shortens the time to market of the end product.
