A business processing device

Abstract

The invention provides a business processing device which is applied to a FPGA (field programmable gate array) chip. The business processing device comprises an upstream business module, a downstream business module and a backward reading main module, wherein all modules are connected together through a bus, the downstream business module receives the data transmitted by the upstream business module, and the data is transmitted by the upstream business module according to a preset time interval; the downstream business module is acquires address information transmitted by the upstream business module through a bus address wire, the address information includes target address information, the downstream business module judges whether the target address information is matched with respective address or not and processing the data if the target address information is matched with the address of the downstream business module, and otherwise, the data is neglected; the backward reading main module is used for caching the data transmitted by the downstream business module to the upstream business module and transmitting the data to the upstream business module. Through the technical scheme, the problems that the expandability of the code is poor and the subsequent function development is not favored when the quantity of the business modules in the FPGA chip is sharply increased can be solved.

Description

technical field [0001] The invention relates to a programmable logic device, in particular to a service processing device. Background technique [0002] With the development of semiconductor process technology, more and more computing and storage modules are integrated in the same chip, making FPGA chips (Field Programmable Gate Array, Field Programmable Gate Array) more and more widely used. FPGA is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. After decades of development, its functions have become increasingly powerful and its cost has become lower and lower. Low-end FPGA chips have gradually replaced traditional digital components, and high-end FPGA chips are constantly competing for the market share of ASICs (Application Specific Integrated Circuits). Therefore, FPGA chips have been widely used in the fields of communication and electronics, and become an important means of realizing electronic systems. [0003] In t...

AI Technical Summary

Problems solved by technology

The existing technology has the following problems. When the number of business modules increases sharply, the scalability of the code is poor. In addition, multi-level arbitration cascades occupy relatively more resources, which cannot make reasonable use of resources, which is not conducive to Subsequent function development
