Description
Technical field
Present invention relates in general to computer realm, more specifically, relate to the indicating device of basic input-output system BIOS program process.
Background technology
Mainboard debug port (PORT80) is a kind of subsidiary function for main board system BIOS (Basic Input or Output System (BIOS)) software development, due to complicacy and the timing dependence of system bios, the operation progress using PORT80 instruction program is a kind of effective mode.The implementation method of PORT80 has a variety of, but the implementation of main flow is not need specific decoding chip will buy separately test chart (being generally pci card) exactly at present.
The main flow implementation of current PORT80 is connected on the south bridge of mainboard by a special CPLD, by resolving the operation to 80 ports in LPC agreement, then by result display with 8 segment numeral pipes.But the program needs special CPLD chip and 8 segment numeral pipes, adds the cost of mainboard and the difficulty of motherboard design, simultaneously also will programming is special in CPLD protocol analysis software.
In addition, PCI test chart software for display can also be used at present to run progress.But such solution needs mainboard to support pci card, and system bios needs to adjust, and needs special PCI test chart, adds debugging cost, and does not generally have PCI slot, so can not be applied on this kind of mainboard due to blade class mainboard.
Summary of the invention
For this reason, the invention provides a kind of indicating device of basic input-output system BIOS program process, comprising: code translator, for representing that the signal of BIOS program data is compiled as 8 bits; First multi-functional input/output port GPIO, is electrically connected with code translator, for simulated clock simulation clock signal, and clock signal is sent to code translator; 2nd GPIO, is electrically connected with code translator, for BIOS program data is converted to signal, and signal is sent to code translator; And indicating device, be electrically connected with code translator, for 8 bits are shown.
Indicating device is 8 LED.
The noble potential of experience clock signal and electronegative potential respectively once, then represent the transmission completing a data bit.
BIOS is the BIOS under same Extensible Firmware Interface UEFI structure.
In addition, additionally provide a kind of indicating device of basic input-output system BIOS program process, comprising: code translator, for representing that the signal of BIOS program data is compiled as binary number; First multi-functional input/output port GPIO, is electrically connected with code translator, for simulated clock simulation clock signal, and clock signal is sent to code translator; 2nd GPIO, is electrically connected with code translator, for BIOS program data is converted to signal, and signal is sent to code translator; And indicating device, be electrically connected with code translator, for binary number is shown.
Indicating device is 8 LED.
Respectively once, then represent the transmission completing a data bit, indicating device need repeat the instruction of 8 secondary data positions for the noble potential of experience clock signal and electronegative potential.
BIOS is the BIOS under same Extensible Firmware Interface UEFI structure.
