SiP-based navigation guidance and control chip

Abstract

A navigation guidance and control chip based on SiP is a GNC chip and comprises a PSOC multi-core information processor bare core, a GNSS satellite baseband bare core, a configuration chip module, a DDR3 bare core and an F ash bare core, the PSOC multi-core information processor bare core comprises a quad-core information processing system PS and a programmable logic PL, and an FPGA+ARM architecture is adopted; the DDR3 bare core comprises two DDR3 circuits which are realized in a microcomponent mode and are connected to a PS part of the PSOC multi-core information processor bare core, and the GNSS satellite baseband bare core is realized in an RDL mode and is connected to a PL part of the PSOC multi-core information processor bare core; the configuration chip module converts a bare chip in a WB form into a bare chip in an FC form through an RDL, and is directly connected with a PS part of the PSOC module; and the chip is realized by two DDR3 circuits through a micro-component mode, and is connected to a PS part of a bare core of the PSOC multi-core information processor. The invention has the advantages of miniaturization, high integration level, low power consumption, high performance and the like.

Description

technical field [0001] The invention mainly relates to the technical field of navigation chips, in particular to a navigation guidance and control chip based on SiP (System in Package, system level package). Background technique [0002] With the development of microsystem technology and new microsystem devices, a large number of miniaturized, low-cost, high-performance GNC (Guidance Navigation and Control, navigation guidance and control) products are increasingly used in small unmanned aerial vehicles, micro Nano satellites, miniaturized guidance systems and other fields. These micro-miniature system platforms put forward strict requirements on the size, size, power consumption and other indicators of GNC components, and also greatly stimulated the research on the miniaturization of GNC systems. [0003] In the existing technology, practitioners continue to invest a lot of manpower and material resources in the research of various key technologies related to GNC microsyst...

AI Technical Summary

Problems solved by technology

[0004] However, the existing GNC microsystem technology is relatively rudimentary. At present, the equipment is mainly based on a general-purpose CPU / MCU and a low-integration interface device to form a single-board system, and then the GNC is further composed of several single-board systems with independent functions. system, poor information fusion, which results in high cost, high power consumption, and large size of the GNC system
