Abstract: An embedded device, a RAM disk of an embedded device and a method of accessing a RAM disk of an embedded device are provided. The embedded device includes: a processing unit, configured to execute an operating system; a first memory, for the processing unit to access required system data when the processing unit executes the operating system; a function module, configured to perform a predetermined function; a second memory, for the function module to access required functional data through direct memory access when the function module performs the predetermined function; and a RAM disk driving module, configured to incorporate a first part of the first memory with the second memory to one RAM disk, and to control access of the RAM disk.

Abstract: A method of processing secure services is provided. The method is applied to a processing unit of a computing device to control the processing unit to process multiple secure services. The computing device includes a storage unit. The method includes: controlling a core of the processing unit to perform following steps in a secure mode: accessing the storage unit to obtain a first command that includes first secure service information, processing a first secure service associated with the first secure service information according to the first command, and accessing the storage unit to obtain a second command that includes second secure service information. During a period from a time point that the core accesses the storage unit to obtain the first to a time point that the core accesses the second command, the core is controlled to stay in the secure mode.
