Noise reducing method for radio portable terminal
A noise reducing method for a radio portable terminal having a radio section for transmitting and receiving radio data, a CPU (Central Processing Unit), connected to the radio section and incorporating a cache, for performing predetermined data processing, and an external memory connected to the CPU, reads an internal operation program runnable only in the CPU from the external memory and stores the internal operation program in the cache prior to reception of the radio data, and then executes only the internal operation program. In this manner, this method suppresses access to the external memory, thereby reducing noise.
