An apparatus for performing downlink or uplink processing in a wireless communication system to maintain efficiency of system bandwidth includes at least one sharing-ring buffer, a MAC-PHY interface, a security engine, and a DMA processor. The sharing-ring buffer is for storing multi-format data. In a situation where the apparatus performs downlink processing, the MAC-PHY interface is for receiving input data, the security engine is for retrieving stored data from the sharing-ring buffer and decrypting the retrieved data, and the DMA processor is for accessing the sharing-ring buffer to obtain the decrypted data. In a situation where the apparatus performs uplink processing, the DMA processor is for receiving input data and storing the input data into the sharing-ring buffer, the security engine is for retrieving the stored data from the sharing-ring buffer and encrypting the retrieved data, and the MAC-PHY interface is for receiving the encrypted data from the sharing-ring buffer.
