CC3200 - Host Processor and Application Processor Shared Memory

Other Parts Discussed in Thread: CC3200

Hi,

I suppose that in CC3200 Cortex-M4 and networking sub-system share memory, right?

I want to receive PCM audio data by I2S in Cortex-M4 and send it directly (raw) on WiFi (so directly I2S ->RAM -> WiFi). Is this OK?

I need WiFi thorughput of 4.6Mbps min, so any sending to networking subsystem via UART (3Mbps max) would not be acceptable, while SPI (20MHz CLK => 20Mbps MAX) might be. But I would surely prefer shared mem.

BR,

Hi Drasko,

I understand your requirement but any access to networking sub-system has to be only through SPI or UART. So direct shared memory access to Networking sub-system is not possible.
