Digital oscilloscope microprocessor hardware design advantages
It has the following advantages: synchronous execution of data processing and system control. The microprocessor is rich in internal storage resources, and adopts the two-level cache structure, which makes the system respond quickly. Peripherals are rich in resources, providing interfaces such as USB interface, RS232 interface and Ethernet interface to connect with PC, so as to facilitate real-time processing and online debugging of waveform data collected from oscilloscope on PC. External storage resources are abundant. DDR2 SDRAM with 1Gbit capacity is used as the post-waveform data cache area and display data cache area, which can store more waveform data and observe more waveform details. It can be seen that the application of the oscilloscope system can greatly improve the data processing ability and waveform capture rate of digital oscilloscope, and the response speed of the whole machine will also go up a step.
