Patent number: 9400861Abstract: There is described a method of optimizing the design of an electronic device with respect to electromagnetic emissions based on frequency spreading. With the method, a designer can, for example, perform a transient simulation on the device only once, and then add frequency spreading with specific parameters by simulation. The resulting frequency spread signal can be observed. The designer can thus evaluate the reduction in electromagnetic emission level, and repeat this process by iteratively applying frequency spreading each time with specific parameters but without having to modify the schematic of the device and to perform another simulation of the device. The method according to this innovation is extremely rapid as the simulation of the design does not need to be repeated at each run of the frequency spreading simulation.Type: GrantFiled: July 7, 2014Date of Patent: July 26, 2016Assignee: Freescale Semiconductor, Inc.Inventors: John Avis Shepherd, Kamel Abouda, Bertrand Vrignon

Patent number: 9390278Abstract: Methods and systems are disclosed for code protection in non-volatile memory (NVM) systems. Information stored within NVM memory sectors, such as boot code or other code blocks, is protected using lockout codes and lockout keys written in program-once memory areas within the NVM systems.

The merged protection register is used to control write access to protected memory sectors. Lockout code/key pairs are written to the program-once area when a memory sector is protected. The program-once area, which stores the lockout code/key pairs, is not readable by external users. Once protected, a memory sector can not be updated without the lockout code/key pair.Type: GrantFiled: September 14, 2012Date of Patent: July 12, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Ross S.
