SPDS106A, a single chip contains an 8-bit RISC microprocessor (CPU) and a 16-bit digital signal processor (DSP), is applied for constituting long duration audio applications. The CPU transmits commands and data to DSP by the means of memory-mapped (parallel interface). The CPU employs 23 general I/Os to access external devices. The 256K x 8 ROM hold the system control program, audio processing program and audio data. The DSP receives the commands and data from CPU and finally runs the decompressing algorithm. Both CPU and DSP share a PWM output for audio.
