Chip for navigation

Abstract

The invention discloses a chip for navigation, and relates to the technical field of navigation guidance and control. The chip comprises a sensor access module, a control output module, an advanced peripheral (APB) bus, an advanced extensible interface (AXI) bus, a variable memory controller (FMC) bus, a first-in first-out memory, a data preprocessing module, a strapdown resolving module, a combined navigation module, a control resolving module, a dual-port RAM module and an RISC-V kernel module. The IP core for navigation has the characteristics of abundant interfaces, high expansibility, high real-time performance, low resource utilization rate and high tailorable capability, and can be widely applied to the fields of unmanned platforms, high-dynamic carriers, personnel state detection, strong impact electromechanical equipment and the like.

Description

technical field [0001] The invention relates to the technical field of navigation guidance and control, in particular to a navigation chip. Background technique [0002] Navigation technology can realize the measurement and calculation of carrier attitude, position, speed and other information, and is the core information source of carrier motion information. With the rapid development of satellite navigation, wireless communication, electronic technology, computer technology, chip manufacturing technology and other fields, navigation technology has developed rapidly. However, with the gradual emergence of requirements such as diversity of product forms, inefficiency of energy consumption, versatility of equipment, richness of interfaces, and real-time computing, existing navigation systems based on combined architectures such as ARM, DSP, and FPGA The algorithm carrying mode is subject to certain restrictions. How to make a dedicated navigation chip with rich interfaces, s...

Problems solved by technology

However, with the gradual emergence of requirements such as diversity of product forms, inefficiency of energy consumption, versatility of equipment, richness of interfaces, and real-time computing, existing navigation systems based on combined architectures such as ARM, DSP, and FPGA The algorithm carrying mode is limited to a certain extent. How to make a dedicated navigation chip with rich interfaces, strong scalability, strong real-time performance, low resource utilization, and strong tailoring ability has always been a difficult problem for domestic navigation and location services.

[0003] For the above problems, no effective solution has been proposed
