SD card non-pluggable programming control device and method for fpga prototype system

Abstract

The present invention proposes a SD card non-pluggable programming control device and method for an FPGA prototype system, the device includes an FPGA module, an upper computer and an SD card expansion board, the upper computer is connected to the FPGA module, the upper computer and the SD card The host computer channel of the expansion board is connected, the FPGA module is connected to the FPGA channel of the SD card expansion board, and the SD device controller of the FPGA module is used to convert the direct address access request issued by the processor core into an SD card operation command and transmit it from the SD card through the FPGA channel. The read data in the SD card of the card expansion board is returned to the processor core, and is also used to generate the corresponding SD card expansion board readable signal according to the control command sent by the host computer and send it to the SD card expansion board through the SD card expansion board control line . The invention can remotely and online control and select the connection path of the SD card expansion board to read, write or burn the SD card, avoiding manual insertion and removal of the SD card.

Description

technical field [0001] The invention relates to the field of control of FPGA prototype systems, in particular to an SD card non-pluggable programming control device and method for FPGA prototype systems. Background technique [0002] By integrating the processor core, the on-chip interconnection network, and the device controller according to the final chip requirements, the system-on-chip (SOC) is implemented in the FPGA system and constructed using the physical devices of the FPGA itself and the FPGA expansion board. A set of FPGA prototype system is a system built with FPGA and its extended equipment as the physical carrier and SOC system as the functional logic. [0003] The FPGA prototype system needs to continuously update the test stimulus during the test process. The test stimulus is stored in the SD card, that is, in the SOC system, the processor core reads and writes data from the SD card through the Internet and the SD card controller, so as to perform A test of ...

Problems solved by technology

This method leads to manual plugging and unplugging of the SD card during work, resulting in the inability to perform remote control, and cannot use automated methods for testing. At the same time, there are hidden dangers in data security. Frequent plugging and unplugging may cause damage to the interface and is not conducive to standardization.
