TMS320C6457: Ethernet MAC of TMS320C6457

Part Number: TMS320C6457
Other Parts Discussed in Thread: SYSBIOS

Hi, 

If the Ethernet MAC of TMS320C6457 is driven by system/bios, and which is embedded in TI DSP?

Thanks.

Derek

  • Hi,

    TMS320C6457 is a TI C64x+ DSP, it has many peripherals, like EMAC, SRIO, EDMA etc, it also has DSP core with L1D, L1P, L2 memory, those all embedded inside the DSP chip. 

    To use the DSP chip, you need software to drive it. This is called driver. It can be very simple C and assembly code in bare metal format, accessing the DSP registers without any operating system. Or, on top of the DSP registers, there are TI CSL (chip support library). On top of CSL, TI has drivers (for example, for the EMAC) and they are provided in the software package and bundled with operating systems, such as TI SYSBIOS. Hope this is clear.
