TCI6638K2K: SRIO data rate and IPC interruption

Rock Su
Intellectual 2220 points
Part Number: TCI6638K2K

Dear colleague,

Our customer has 2 issues, could you give us some solutions?

1. SRIO speeds up.

They are currently testing SRIO rate only 1.6 Gbps, but they hope the lowest date rate is 2 Gbps, they check TCI6638 datasheet, it could support the rate, so how to improve SRIO data rae?

2. The ipc interruption between ARM and DSP , because they do DSP first, so they need to move ARM ipc interface backward to implement the communication between different nuclear, and eliminate the influence of the development of DSP. Do we have related code?

Thanks a lot!

Best Regards,

Rock Su

    Hi, Rock,

    1) Is SRIO configured by DSP running RTOS? In Processor SDK, SRIO is not supported any more.

    2) Are you asking about IPC interrupt between ARM and DSP, and is it Linux on ARM and RTOS on DSP? K2K has IPCGRx registers for the interrupts between ARM and DSP. You can take a look at the K2K datasheet.
