“…And then, DSP fetches data and enables essential calculations immediately, whereas the processor of computer is only responsible for the command interaction and data collection. In [2], the core processor of the four-axis motion controller is the DSP chip TMS320F2812, which interacts with external devices via limited number of buses under I/O mode. The floating-point DSP chip TMS320F28335 can adjust the data size transferred each time and achieve better communication performance via new added six-channel DMA bus, which has a base of four cycles/word.…”

Abstract. To enhance the efficiency and stability of real-time data acquisition and transmission in motion control process, a high-speed realtime communication architecture based on FPGA and DSP is developed in this paper. The direct-memory-access (DMA) control module initiates DMA transfers over the peripheral-component-interconnect (PCI) bus. After that, two first-in-first-out (FIFO) buffers work as caches and convert data widths between the PCI bus and the local bus. Consequently, the data caches can be accessed by DSP over the local bus under DMA mode. The size of data transferred each time is able to be adjusted according to the application requirements. Experiments are carried out to demonstrate that the proposed communication architecture is capable of achieving high speed and stability in data communication with low consumption of compute resources.
