BITWISE WRITING APPARATUS FOR SYSTEM-ON-CHIP SYSTEM

Title:

BITWISE WRITING APPARATUS FOR SYSTEM-ON-CHIP SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/128987

Kind Code:

A1

Abstract:

Provided is a bitwise writing apparatus for a SOC system. The apparatus includes a slave device interface module, a decoding module and a master device interface module. The slave device interface module is configured to receive a write request sent by a master device interface of a bus controller and send the write request to the decoding module. The decoding module is configured to receive the write request sent by the slave device interface module, decode the write request and send valid information after the decoding to the master device interface module. The master device interface module is configured to receive the valid information sent by the decoding module, read data in a destination address, perform a bitwise operation for the read data to obtain new data, send a write request to a slave device interface of the bus controller and write the obtained new data into a peripheral register corresponding to the destination address. The system can effectively reduce the instruction storage space and thereby reduce the chip area and lower the chip cost.
