Abstract: A system for real time clock (RTC) calibration includes: a timer counter; a clock generator; and a clock calibration unit coupled between the clock generator and the timer counter. The clock calibration unit receives calibration parameters comprising an average calibration value, a remainder calibration value and a calibration period, counts a plurality of clock cycles generated by the clock generator, calibrates a number of the counted clock cycles according to the average calibration value and remainder calibration value in the calibration period, and increments the timer counter by one second when a predetermined number of clock cycles have been reached.

Abstract: In one embodiment of the invention, an apparatus for authenticating a flash program is provided. The apparatus comprises a hardware unique key, a register storing a customer identity (ID) and a message authentication code (MAC) generation unit. The MAC generation unit acquires a root key corresponding to the hardware unique key and the customer ID, and generates a MAC for the flash program using the acquired root key, wherein the content of the register is locked to avoid modification of the stored customer ID until the next system reset.

Abstract: A wireless apparatus, an integrated circuit, and a method thereof. The wireless apparatus, providing hardware security, comprises a secure memory and a secure Integrated Circuit (IC). The secure memory comprises security authentication data. The secure IC, coupled to the secured memory, comprises a processor, a security controller, a security pin, and a read only memory (ROM). The processor is configured to process data. The security controller, coupled to the processor and the secure memory, translates the security authentication data to the processor. The security pin, coupled to the security controller, enables security of the secure IC. The ROM, coupled to the processor, has stored thereon instructions determining a security level according to the security authentication data and the security of the secure IC. The instructions are executed by the processor upon a boot-up operation.

Abstract: A method of changing configurations of a mobile phone based on a status of unhandled events includes generating an unanswered factor to record a number of unhandled events received by the mobile phone; receiving an incoming event on the mobile phone, the incoming event being a received phone call or a received message; updating the unanswered factor in response to receiving the incoming event; and executing a first managing process when the unanswered factor exceeds a predetermined threshold.

Abstract: Boot systems and methods. A processing unit decrypts a first ciphertext in first memory to generate a first plain text comprising a jump instruction of a first specific address of the first memory, stores the first plain text at a first address of second memory, and executes the first plain text at the first address. The processing unit decrypts a second ciphertext in the first memory to generate a second plain text, stores the second plain text at a second address of the second memory, and executes the second plain text at the second address. A boot procedure of the device proceeds after the execution of the second plain text.
