S5PC110_UM
The audio subsystem comprises of the following blocks:
• RP: Specifies the DSP core, which is an audio-dedicated DSP for S5PC110.
• IMEM and DMEM: IMEM is used for instruction cache of RP, while DMEM is used for data memory of RP. If
RP is not used, the external modules in audio subsystem use IMEM and DMEM for SRAM (IMEM: 64KB and
DMEM: 96KB).
• IBUF_0, IBUF_1: Specifies input buffers 0 and 1. 18KB is allocated for each input buffers in RP. These buffers
are used by external audio subsystem as data reservoir. There are Endian Converters (ECs) besides IBUF_0
and IBUF_1.
• OBUF_0, OBUF_1: Specifies output buffers 0 and 1. 9KB is allocated for each output buffers in RP. These
buffers can be used by external audio subsystem as data reservoir.
• ASS_CLKCON: Specifies the internal clock controller in audio subsystem.
• COMMBOX: Specifies the communication channel between ARM and RP.
• I2S V51: Specifies the main I2S module of S5PC110.
