Embodiment Construction

[0035] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes.

[0036] The present invention provides a chip architecture based on the extended function of the open system bus, such as figure 1 ,

[0037] It includes: a main control chip 1, a slave function chip 2, the main control chip 1 and the slave function chip 2 adopt the same bus protocol, and realize data communication and control between the two through the system bus.

[0038] The bus protocol-related signals of the main control chip are drawn out through the pins of the first chip; the bus protocol-related signals of the slave function chip are drawn out through the pins of the second chip; the pins of the first chip and the pins of the second chip are correspondingly connected by binding wires; The control chip and the ...

Abstract

The invention provides an open system bus expansion function-based chip architecture. The function of a chip is expanded by opening a system bus to pins of the chip; and without redesign, a main control chip with an open bus port only needs to be matched with other slave function processing chips with open bus ports, repackaging is performed, and mass production test related processes are correspondingly added, so that the main control chip can be upgraded to a new universal control chip product with functions of the slave function chips. Under the architecture, the main control chip and the slave chips are combined more closely and cooperate more reliably, and the data transmission speed is greatly increased. The market time of the new product is greatly shortened, thereby effectively assisting in seizing market opportunities. Moreover, the slave function chips and the main control chip adopt most proper technological processes respectively; and the new universal control chip is formed, thereby realizing comprehensive optimal performance and cost.

Description

technical field [0001] The invention relates to the field of integrated circuit chips, in particular to a chip architecture based on open system bus extension functions. Background technique [0002] With the rise of the Internet of Things and mobile smart devices, various new applications have emerged, such as smart audio, Mobike, wireless charging and other popular applications, and there are more and more requirements for chips. The corresponding general control chip The industry has also started a new round of vigorous development. Whether it is a major international manufacturer or a new company, it is difficult to provide chips in a short time to meet various functional requirements. In this case, a chip with expandable functions has obvious advantages in meeting various needs compared with the traditional solution where multiple chips are used together. [0003] There are two ways to expand chip functions, one is based on specific storage interface standards; the ot...
