Abstract: A radio paging apparatus (100) with an LPC speech synthesizer (112). The paging apparatus of the present invention includes a controller and decoder (106), and a microprocessor controlled speech synthesizer (112) both coupled to a dual port memory (110). Digitally encoded voice messages are stored in a dual port memory (110) which includes a scratch pad area for storing control words and address pointers which indicate the attributes and location of stored digitally encoded voice messages. Messages are reconstructed by reading the control words and address pointers and processing the information stored in memory (110) with a speech synthesizer (112). The structure is adapted to store and process LPC encoded signals and it permits a message to be stored while another is being reproduced. In addition, information contained in the control words permits old or read messages to be discarded if a new message must be stored.

Abstract: A microcomputer (104) having predetermined clock pulse frequency requirements receives pulses from a multiplying type frequency synthesizer (200) which utilizes a reference frequency less than the largest of the predetermined requirements. The synthesizer (200) is responsive to program instructions to generate clock pulse frequencies sufficient to satisfy the requirement for immediate execution of programmed tasks. As the execution requirements change, the synthesizer (200) responds to provide only the frequency required. Thus, the power dissipated by the entire microcomputer system is minimized.
