Abstract
A method and apparatus for executing an application program stored in an one-time-programmable, OTP, memory in a system on chip (SoC) is described. The SoC has RAM, a CPU and an OTP controller. The OTP memory stores an application program. The method includes, by the processor unit at power-up, instructing the OTP controller to copy the application program from the OTP memory to RAM, executing the application program from RAM, and setting the system on chip (SoC) in sleep mode. By the OTP controller after a wake-up, copying the application program from the OTP memory to the RAM and after the copying, waking up the CPU and transferring control back to the CPU. By the CPU after being woken up by the OTP controller, executing the application program from RAM.
