Abstract

The invention provides a system-on-a-chip and a configuration method of hardware programmable devices of the system-on-a-chip. The system-on-a-chip comprises a central processing unit, a software memory, a software download and debugging interface, hardware programmable devices, a hardware configuration unit and a hardware configuration information download interface, wherein the central processing unit is connected with the software memory, the software download and debugging interface and the hardware configuration unit, and the hardware programmable devices are connected with the hardware configuration unit and the hardware configuration information download interface. The system-on-a-chip further comprises a hardware configuration management unit connected with the central processing unit, wherein the hardware configuration management unit is used to generate control signals which instruct the central processing unit to configure a corresponding hardware programmable device, is used to control the central processing unit to read configuration information of the corresponding hardware programmable device from the software memory, and is used to configure the corresponding hardware programmable device.

Description

technical field [0001] The invention relates to programmable device technology, in particular to a system on a chip and a configuration method of a hardware programmable device of the system on a chip. Background technique [0002] System-on-a-chip (SOC) refers to the integration of a complete system on a single chip, including the central processing unit (CPU), memory, and peripheral circuits, etc., for all or part of the necessary electronic circuits. Packet grouping technique. [0003] Products using SOC generally use a SOC chip as the main control chip of the product system. The SOC chip realizes the function of the product through its own hardware IP or developing embedded software. For the first method, because it is customized in the SOC chip, the cost is relatively low, but many functions cannot be changed, and the technical confidentiality of the product is relatively weak; in the second method, soft IP can meet the requirements of individual functions, but in term...
