Problems solved by technology

In addition, limited by the transmission mode of the existing Industry Standard Architecture (ISA), data can only be transmitted in 8-bit length
Since the processing speed of the central processing unit is often much faster than that of the embedded controller, the existing communication mechanism between the basic input output system and the embedded controller will greatly reduce the operating performance of the entire computer

Abstract

The invention provides a data processing device of a basic input output system (BIOS). The device comprises a BIOS unit, a shared memory and a control unit, wherein the shared memory is used for providing the BIOS unit for writing in command data, and identification data in the command data is stored in an identification field; the control unit is used for reading and executing the command data according to a value expressed by the identification data in the identification field and writing back-pass data into the shared memory for the BIOS unit to read the back-pass data from the shared memory; and the back-pass data is a result of the control unit for executing the command data and comprises the identification data.

Description

technical field [0001] The present invention relates to a data processing device, and in particular to a basic input output system (Basic Input Output System, BIOS) data processing device. Background technique [0002] When transferring data between the existing basic input and output system and the embedded controller (Embeded Controller; EC), it is necessary to first test whether the embedded controller is in a busy state through the input / output port (I / 0port). Only when the device is not in a busy state can it communicate with the embedded controller, such as issuing instructions to the embedded controller, or waiting for the embedded controller to return the result of processing data, etc. In addition, limited by the transmission mode of the existing Industry Standard Architecture (ISA), the data can only be transmitted with a length of 8 bits. Since the data processing speed of the central processing unit is often much faster than that of the embedded controller, the ...
