Abstract: A method of securing a data frame is provided. The method includes receiving a request from a memory client to read or write decoded data in a memory. The memory may be partitioned to have a secure memory region and an unsecure memory region. The method also includes determining if the request is associated with the secure memory region or the unsecure memory region. The method also includes determining whether the memory client has access privileges to the secure memory region if the request is associated with the secure memory region. The method also includes granting the request if the memory client is determined to have access privileges.

Abstract translation: 提供了一种保护数据帧的方法。 该方法包括从存储器客户端接收请求以读取或写入存储器中的解码数据。 存储器可以被分割成具有安全的存储器区域和不安全的存储器区域。 该方法还包括确定请求是否与安全存储器区域或不安全存储器区域相关联。 该方法还包括如果请求与安全存储器区域相关联，则确定存储器客户端是否具有对安全存储器区域的访问权限。 如果确定存储器客户端具有访问权限，则该方法还包括授予请求。
