Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accuse that Computer Architecture mainly comprises four parts such as operating system, firmware, hardware circuit and physical construction, as shown in Figure 1.Improve overall performance and improve structural design and mainly by following three aspects: measure, complete.
1, the overall lifting of computing machine overall performance, depends on that Godson 3A processor host frequency and internal memory frequency of operation improve.The high primary frequency of Godson 3A processor design is 1GHz, and internal memory maximum operation frequency is 800MHz, in order to make computing machine steady operation take following design at highest frequency:
(a) improve Power supply design, adopt heterogeneous power supply technique, strengthen the reliability of power supply; Adopt three ground isolation technologies, digital circuit and mimic channel ground wire are separated, reduce the interference of numeral and simulating signal.
(b) optimize PCB placement-and-routing, when PCB design to plate on components and parts carry out rational deployment and subregion, reduce the interference between numeral, mimic channel, and carry out targetedly isometric coupling, impedance Control etc., raising signal lead quality.
(c) by software test pointedly, the most effective software parameter of configuration.By the multiple different memory parameters of firmware configuration, utilize the validity of multiple testing software checking memory parameters, according to test result, choose the most reliable and the most stable parameter configuration.
2,, in order to improve the networking capability of system, design abundant communication interface and mainly carried out following three aspects: design:
(a) select to have the Super IO chip that enriches UART serial port function, scheme reasonable in design realizes 6 road RS422 serial ports and 2 road RS232 serial port functions, realizes principle as shown in Figure 2.
(b) PCB printed board needs reasonable line arrangement, causes interference while avoiding multi-channel serial port transceiving data, improves circuit reliability.
(c) will be in kernel and PMON during Software for Design reasonable disposition interrupt source, solve the phenomenon that produces data packet loss while receiving Big Dipper data.
