Design method of commercial satellite control processor chip

Abstract

The invention provides a design method of a commercial satellite control processor chip, which comprises the following steps of: confirming the specifications of the processor chip, such as processing capacity, external interface and input and output requirements of programmable logic; counting function pins of the chip, including function names, electrical characteristics and the like; counting the power supply types of the chip, and estimating the number of pins according to the power supply current of each type of power supply; drawing PINMAP according to the number of the chip function pins, the number of the power supply pins and the number of the loop pins, and completing preliminary design of chip wiring. The method has a function of configuring part of pin logic, and is very high in applicability.

Description

technical field [0001] The invention relates to the field of chip design, in particular to a method for designing a satellite control processor chip. Background technique [0002] Compared with traditional satellites weighing several tons, commercial satellites have the characteristics of small size, light weight, and low launch cost. In recent years, with the continuous growth of people's demand for navigation enhancement, satellite-ground communication, disaster monitoring and other fields, the launch mission of commercial satellites has shown the characteristics of blowout growth. [0003] The control computer is the control center of commercial satellites, and it is a very important on-board product to ensure the success of the launch and the completion of tasks in orbit. [0004] It is generally composed of transponder, processor board (active and standby redundant configuration), signal conditioning board, GPS receiving module, payload data receiving and processing mo...

Problems solved by technology

The processor chips produced by foreign component manufacturers are designed and produced for the general industrial control field or the consumer electronics field, not the optimal design for domestic aerospace electronic products; while the ASIC devices customized by domestic institutes are only suitable for a certain series of spacecraft Product use, the development cost after amortization is too high, and there are no programmable logic input and output pins, it needs to be used in conjunction with FPGA or CPLD products, and the cost cannot be further reduced

Neither model is optimal for commercial satellite control processor chips
