Embodiment 1

[0015] Such as figure 1 The shown signal data exchange board includes a backplane bus, the backplane bus is connected with FPGA, the first SRIO SWITCH and the second SRIO SWITCH, the first SRIO SWITCH and the second SRIO SWITCH are connected in series, and the FPGA The PPC is also connected to the first SRIO SWITCH, and the PHY chip, Uart, DDR2 SARAM and NOR FLASH memory are connected to the PPC.

[0016] In the present embodiment, FPGA is a field programmable gate array; SRIO SWITCH is a SRIO SWITCH ZD switching board; PPC is a PowerPC, which is a CPU of a RISC architecture; a PHY chip is an Ethernet PHY chip; Uart is a universal asynchronous transceiver transmitter; DDR2 SDRAM stands for Random Access Memory.

[0017] In this embodiment, the signal enters the PPC through the Uart and the PHY chip, performs signal processing through the PPC, and performs data exchange through two SRIO SWITCHs connected in series, so that the two SRIO SWITCHs can exchange data separately and ...

Embodiment 2

[0019] This embodiment adds the following structure on the basis of Embodiment 1: the FPGA is connected with DDR2 SARAM and GPIO.

[0020] In this embodiment, the DDR2 SARAM of the FPGA can realize data storage or redundant backup, and multiple DDR2 SARAMs can be set, and the GPIO (that is, the bus expander) can realize multi-thread output of data, which is convenient for data usage of multiple devices.

Embodiment 3

[0022] In this embodiment, the FPGA is optimized on the basis of Embodiment 1 or Embodiment 2, specifically: the FPGA model is XC6SLX100.

[0023] The XC6SLX100 in this embodiment has superior performance, low cost and power consumption, fast processing speed, can realize signal processing well, and reduce energy consumption at the same time.

Abstract

The invention discloses a signal data exchange board comprising a backplane bus. The backplane bus is connected with an FPGA (field programmable gate array), a first SRIO (serial rapid I / O) SWITCH and a second SRIO SWITCH. The first SRIO SWITCH and the second SRIO SWITCH are connected with each other in series. The FPGA and the first SRIO SWITCH are connected with a PPC (power personal computer) respectively. A PHY (physical layer) chip, a UART (universal asynchronous receiver / transmitter), a DDR2 (double data rate 2) SARAM (static random access memory) and a NOR FLASH are connected to the PPC respectively. The Power PC signal data exchange board has the advantages of rapid data exchange speed and low power consumption, and is high in stability and reliability.

Description

technical field [0001] The invention relates to a signal data exchange board, more specifically to a signal data exchange board. Background technique [0002] Now that the signal exchange technology is becoming more and more mature, various signal exchange devices have appeared. The common router in life is a kind of data switch; in some special fields such as radar communication, navigation and aerospace data exchange equipment, it needs to meet high exchange requirements. Speed ​​and signal accuracy, and because there are many devices, multiple different ports are required for data exchange, which requires the exchange device to have high data exchange speed, stability and multi-port support. For this reason, we designed A high-speed and stable signal data exchange motherboard. Contents of the invention [0003] The invention provides a signal data exchange board, which solves the problems of slow signal data exchange speed, poor stability and reliability in the past. ...
