Embodiment Construction
[0012] The implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples.
[0013] The present invention integrates eight 600MHz high-performance floating-point DSP processors on a standard 6U cPCI board, and the entire board can provide 28.8GFLOPS peak computing capability, which is suitable for real-time signal processing, such as radar, sonar, electronic countermeasures, etc. The application field of high-speed data acquisition and processing.
[0014] The system bus adopts 66MHz 64bit cPCI bus, and 8 TS201S processors do not share the bus, and adopt distributed memory architecture. The 64-bit bus of each TS201S seamlessly connects 4 pieces of 32M×16-bit SDRAM, and the 4 pieces of SDRAM are configured as 32M×64-bit, with a total of 256MB. The SDRAM capacity of the whole board is 256MB×8=2048MB. Both cPCI host and DSP can access SDRAM. The peak rate of DSP accessing SDRAM is 800MB / S, and the pea...

The invention discloses a universal array signal processing plate and belongs to the field of signal processing. The universal array signal processing plate comprises a digital signal processing (DSP) module, a coprocessing module, an internal memory and flash memory module, a power supply and clock module and a compact peripheral component interconnect (cPCI) interface module, wherein the DSP module consists of eight signal processing chips; the coprocessing module consists of four field programmable gate arrays (FPGA) and a complex programmable logic device (CPLD); the internal memory and flash memory module consists of a synchronous dynamic random access memory (SDRAM) and a FLASH memory; the power supply and clock module supplies power to the signal processing plate and provides a working clock for each chip on the plate; the cPCI interface module consists of a cPCI bus and a PCI-bridge chip; the cPCI bus is used for transmitting data information, address information and control information at a high speed; and the PCI-bridge chip is used for providing a data channel between non-PCI equipment and the PCI bus. The signal processing plate avoids sharing the bus, greatly reduces data transmission quantity of the bus and effectively alleviates bus competition.
Description
technical field [0001] The invention relates to a general array signal processing board, which belongs to the field of signal processing. Background technique [0002] As the signal processing system has higher and higher requirements for calculation and data transmission capabilities, a multi-DSP parallel signal processing platform has emerged as the times require. In order to facilitate the communication and task division between each DSP, the current multi-DSP processing platform takes the tightly coupled structure of sharing / multiplexing bus as the mainstream design. The shared / multiplexed bus not only needs to complete the communication between DSPs, but also completes the communication between DSPs and A / D, D / A, serial ports, USB devices, network ports, etc., which is likely to cause bus competition between data processing. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a general array signal...
