Global bus
The global bus is compatible with the TIM standard.
The Global Bus Interface is a memory Interface that follows Texas Instruments’
TMS320C4x External Bus operation standard. Additional information on the standard
is available in the
TMS320C4x User’s Guide chapter 9:
External Bus operation .
When Writing, the FPGA sends data across the global bus to the external device.
When Reading, the external device writes data across the global bus to the FPGA.
