DS
FR304 is a part of Yangjie DS, a low-cost, high-performance digital signal processor (DSP) for digital signal processing applications. It is based on a high-performance RISC processor, a multimedia accelerator, a digital video coprocessor, and many peripheral functions. It is designed to provide a cost-effective way to develop and embed advanced digital signal processing algorithms into applications. It has a wide range of on-chip peripherals, such as an SPI (Serial Peripheral Interface), UART (Universal Asynchronous Receiver/Transmitter), GPIO (General Purpose Input/Output), and multiple timers. It also includes support for high-performance DSP algorithms, such as Fast Fourier Transform (FFT), Finite Impulse Response (FIR) filters, and adaptive filters. The FR304 also offers extensive system functions, such as power monitoring, wake-up from low power mode, system boot loader, and clock frequency adjustment.
