Data cache system, method and aerospace electronic device

Abstract

The invention discloses a data cache system, method and aerospace electronic device. The system comprises: FPGA and multiple asynchronous SRAM chips; the FPGA comprises: a plurality of data interfaces, a control interface, and an address interface; the plurality of data interfaces are respectively connected to the data signal input and output interfaces of the corresponding asynchronous SRAM chips, the control interface is connected to the control signal input interfaces of the plurality of asynchronous SRAM chips, and the address interface is connected to the address signal input interfaces of the plurality of asynchronous SRAM chips; The FPGA issues a control signal, an address signal, and a plurality of sets of data signals corresponding to the number of asynchronous SRAM chips, and controls the plurality of sets of data signals according to the control signal and the address signal simultaneously to be stored in the plurality of asynchronous SRAM chips. In the background of aerospace applications, the system uses multiple asynchronous SRAM chips, which greatly improves the data cache speed, occupying very small FPGA resources and simplifying FPGA software design. It has less performance dependencies on FPGA devices and less impact on other FPGA functions.

Description

technical field [0001] The invention relates to the field of aerospace electronics, in particular to a data cache system, method and electronic equipment for aerospace. Background technique [0002] With the rapid development of aerospace application technology, high-speed acquisition units are widely used in electronic systems of space vehicles such as communication satellites and remote sensing satellites, and broadband high-speed storage technology is a key part of high-speed data acquisition units, and its storage bandwidth determines Maximum acquisition speed. In addition, the demand for data acquisition speed of current aerospace electronic application equipment is increasing by leaps and bounds, from the original several Msps to tens of Msps (Mega samples per second "1 trillion samples per second, the unit of sampling speed") level has been greatly improved Increased to hundreds of Msps, so the current aerospace electronic application equipment has a higher demand fo...
