随着科学技术的飞速发展,数据采集已经广泛地应用于我们的生产生活中。选用的TMS320VC5402拥有改良的增强型的HPI,主机和DSP都能访问HPI存储器,异步的主机访问可以在HPI内部重新得到同步。HPI支持主机与DSP之间高速传输数据。PCI9052的局部总线设置为8位局部总线,采用地址数据非复用模式,实现与TMS320VC5402的接口。并采用TLC5510芯片实现高速并行AD转换。
With the rapid development of science and technology, data collection has been widely used in our production and life. The TMS320VC5402 is available with an improved, enhanced HPI that enables both host and DSP to access HPI memory and asynchronous host access to regain synchronization within HPI. HPI supports high-speed data transfer between the host and the DSP. PCI9052 local bus is set to 8-bit local bus, using non-multiplexed address data mode, and TMS320VC5402 interface. And TLC5510 chip using high-speed parallel AD conversion.
