Collection plan (1)

TI C5000 DSP has the characteristics of low power consumption, high performance and low cost. Among them, TMS320VC5502 has a clock speed of up to 300M, can expand 2MB of sdram, has rich interfaces, 16K instruction cache, 64KB on-chip DRAM, and internal 6-channel DMA. These features make it very suitable for high-speed data acquisition systems.

ISP1581 is a USB2.0 chip produced by Philips. It supports USB2.0 high-speed communication, has its own FIFO, and supports DMA. It is widely used in MP3, USB mess storage, Ethernet, printers, scanners and other devices.

The following is the TMS5502+ISP1581 development board I use:
