Embodiment Construction

[0015] Such as figure 1 As shown, this method of downloading code streams in different formats to FPGA includes the following steps:

[0016] (1) Define the different formats of the code stream, and process the initial code stream accordingly, so that the number of bits contained in the code stream file meets specific requirements, and obtain the code stream of the corresponding format;

[0017] (2) Adopt a unified conversion algorithm to convert the psk format into the corresponding flash_psk format;

[0018] (3) Define the transmission protocol of the small box, and use a unified transmission method to transmit the flash_psk format file to the Flash device.

[0019] The present invention starts from the initial code stream, and obtains a code stream file of uniform length after processing the initial code stream; the compression algorithm and encryption algorithm are not limited to a specific algorithm, and can be replaced by other algorithms with the same function accordin...

Abstract

The invention discloses a method and a system for downloading code streams in different formats to an FPGA, which greatly simplify the code stream downloading process, can accurately and efficiently transmit the code streams in different formats to the FPGA and improve the flexibility and the efficiency. The method for downloading the code streams in different formats to the FPGA comprises the following steps of: (1) defining different formats of the code streams, and correspondingly processing the initial code streams, so that the number of bits contained in a code stream file meets a specific requirement to obtain the code streams in the corresponding formats; (2) carrying out a uniform conversion algorithm to convert the psk format into a corresponding flash psk format; and (3) defining a transmission protocol of the small box, and transmitting the flash psk format file to the Flash device by adopting a uniform transmission mode.

Description

technical field [0001] The invention relates to the technical field of programmable logic devices, in particular to a method for downloading code streams in different formats to FPGA, and a system for downloading code streams in different formats to FPGA. Background technique [0002] In FPGA (Field-Programmable Gate Array, Field Programmable Gate Array) chip circuit design, EDA (Electronics Design Automation, Electronic Design Automation) software obtains code stream files based on user circuit design files and chip information. In order to adapt to different usage scenarios, code stream files have many different formats, such as original format, compressed format, encrypted format and so on. Configuring these bitstream files to FPGA is a key step. [0003] At present, the allocation of code stream files in different formats to the FPGA is targeted, which limits the method used. At the same time, due to the lack of unified processing, the conversion algorithm and downloadi...
