Multi-processor system including memory shared by multi-processor and method thereof

A multi-processor system comprising:

• a first processor;
• a second processor;
• and
• a memory interface circuit,
• the second processor being configured to generate a second address descriptor, and request the memory interface circuit to store the second address descriptor in common memory, the second address descriptor including address information indicating a location in the common memory at which deciphered data is to be stored,
• the memory interface circuit being configured to store the second address descriptor in the common memory according to the request of storing the second address descriptor from the second processor,
• the first processor being configured to generate decoded data by demodulating and decoding a signal received through wireless communication, and request the memory interface circuit to store the decoded data in a common memory,
• the memory interface circuit being further configured to,
• in response to the request of storing the decoded data from the first processor, store the decoded data generated by the first processor in the common memory,
• read the decoded data stored in the common memory,
• generate the deciphered data by deciphering the decoded data read from the common memory, and
• store the deciphered data generated by the memory interface circuit in the common memory based on the second address descriptor stored in the common memory.
