Problems solved by technology

[0014] The disadvantages of Shanghai’s high-performance solution are: the speed of loading SROM through the uC / OS II system is slow; the process of reading HMCODE and BIOS through the South Bridge LPC interface under the active guidance of the SROM is complicated and the reading speed is slow; the hardware is complex and the uC / OS II system takes up A large number of FPGA logic resources, high cost

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings:

[0044] like Figure 4 , Figure 5 and Image 6 As shown, the method for quickly guiding the BIOS of Shenwei processor described in the present invention is realized by FPGA (Field Programmable Gate Array), and the following controllers are designed in the FPGA:

[0045] Maintenance interface controller: used to send different maintenance packages to control the processor, including resetting, loading SROM, and requesting to obtain the operating status, and at the same time obtain the operating status of the processor by parsing the received maintenance package; Figure 5 As shown, the maintenance interface controller first packs the data of other controllers in the FPGA, then converts the serial-to-parallel data to the maintenance interface, and converts the data from the maintenance interface to parallel to serial, then parses the packets and sends them to other con...

Abstract

The invention discloses a method for rapidly guiding a BIOS (basic input output system) of a ShenWei processor. The method is realized through an FPGA and controllers are designed in the FPGA as follows: a maintenance interface controller, an SROM loading controller, a memory writing controller, a startup guiding controller, a PCIE controller and a storage controller. The method comprises steps as follows: resetting; initialization operation; query of the initial state; query of the initial memory state; startup of the SROM loading controller; running of an SROM after loading of the SROM, and waiting of SROM initial memory; query of the initial memory state; startup of the memory writing controller; startup of the BIOS after loading of HMCODE and BIOS. Guide of the BIOS of a ShenWei processor computer is accelerated passively, the guide process is simplified, the guide speed is increased, hardware circuits are simplified, and the hardware cost is saved.

Description

technical field [0001] The invention relates to a method for guiding the BIOS of a Shenwei processor, in particular to a method for quickly guiding the BIOS of a Shenwei processor based on passive guidance. Background technique [0002] Shenwei processor is a Chinese-made high-performance processor manufactured by Shanghai High-performance Integrated Circuit Design Center, with completely independent intellectual property rights. [0003] Shenwei processors use the domestic platform BIOS of Baiao Software. Shenwei processors need to go through three steps to boot BIOS: run SROM, import HMCODE, and run BIOS. Generally, the quick boot of the BIOS of the x86 motherboard is to reduce the running time of the BIOS by not displaying the LOGO to achieve the purpose of quick boot. [0004] For ease of understanding, the following first describes some software and hardware involved in the Shenwei processor: [0005] BIOS: The English full name is Basic Input Output System. It is a s...
