Abstract
A multi-processor system includes a first processor; a second processor; a common memory configured to store data generated by the first processor and data generated by the second processor; and a memory interface circuit configured to interface between the common memory and the first and second processors, the first processor being configured to demodulate and decode a signal received through wireless communication, and store the decoded data in the common memory via the memory interface circuit, the memory interface circuit being configured to read and decipher the decoded data stored in the common memory, and store the deciphered data in the common memory.
Claims10
A method of operating a multi-processor system including a first processor and a second processor, the method comprising:
- the first processor receiving data through wireless communication and generating first packet data based on the data, where the first processor is a connectivity processor (CP) and the first packet data is an Internet protocol (IP) packet;
- the first processor storing the first packet data in a first-processor allocation region of a common memory;
- a memory interface circuit reading the first packet data from the first-processor allocation region and generating deciphered data by deciphering the first packet data;
- the memory interface circuit storing the deciphered data in a second-processor allocation region of the common memory;
- and
- the second processor reading the deciphered data from the second-processor allocation region and processing the deciphered data.
