Chip design method based on RISC-V, navigation chip and receiver

Abstract

The invention discloses a chip design method based on RISC-V. The chip design method comprises the following steps: dividing the interior of a chip into a power supply part, a large system part and asmall system part; the power supply part supplies power; a main core, a large system bus bridge and a plurality of large system sub-modules are designed in a large system part and used for completingall functions of a chip; an RISCV core, a small system bus bridge and a plurality of small system sub-modules are designed in a small system part and used for power consumption management and auxiliary work after a main core is powered down. And the large system bus bridge and the small system bus bridge are connected and carry out communication and data interaction. The invention also discloses anavigation chip designed by adopting the chip design method based on RISC-V. The invention also discloses a receiver comprising the navigation chip and a chip design method based on RISC-V. The powerconsumption of the chip can be effectively reduced, the universality is high, and the reliability is good.

Description

technical field [0001] The invention belongs to the field of chip design, and in particular relates to a RISC-V-based chip design method, a navigation chip and a receiver. Background technique [0002] With the development of economy and technology, chip design has been extensively developed. With the reduction of process feature size and the increase of complexity, the power consumption density per unit area of ​​the chip has risen sharply, and has reached the limit that packaging, heat dissipation, and underlying equipment can support; heat dissipation and reliability issues also require IC performance. The smaller the consumption, the better. For the current popular mobile devices, the complexity of SoC design is getting bigger and bigger, and the requirements for power consumption are getting higher and higher. In the chip design industry, low-power technologies emerge in an endless stream, and major chip companies are paying more and more attention to them. The low-po...
