Abstract

The embodiment of the invention provides a data transmission processing method and device which are used for an integrated tester chip, the integrated tester chip comprises a processing system PS side and a programmable logic PL side, the PS side comprises universal serial bus USB equipment controller hardware and character equipment, The method comprises the following steps: when USB equipment controller hardware receives a data writing request from an upper computer, storing first data corresponding to the data writing request into a buffer area of character equipment; reading the first data from the buffer area based on the user mode, and sending the first data to the PL side; when the PS side receives second data from the PL side, storing the second data into the buffer area based on the user mode; and when the USB equipment controller hardware receives a data reading request from an upper computer, sending the second data in the buffer area to the upper computer. According to the embodiment of the invention, the rate of data interaction between the comprehensive tester and the upper computer can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data transmission processing method and device. Background technique [0002] The radio comprehensive tester (abbreviated as the comprehensive tester) is an instrument that can accurately measure the radio frequency indicators of multi-standard terminals. The comprehensive tester can be widely used in the calibration and testing of terminal production, as well as in the fields of terminal and chip R&D and design, and can also be used in terminal radio frequency conformance certification testing. From the perspective of improving the efficiency of terminal production and R&D testing, the cost of testing can be minimized. [0003] Usually, data exchange is performed between the comprehensive tester and the host computer through Gigabit Ethernet. Take the chip used by the comprehensive tester as an example of the SOC (System-on-a-Chip, System-on-a-Chip) ch...
