Abstract
A heterogeneous integrated circuit having a digital signal processor and two programmable logic cores, PLCs. An AMBA AHB couples the cores and most other functional units on the IC. The PLCs are also coupled to the DSP through a separate DMA sharing unit to the DSP, and particularly to the DSP memory. The memory sharing arrangement provides a separate high-speed data transfer mechanism between the PLCs and the DSP. The AMBA AHB allows the DSP to control the PLC operations without interference with high-speed data transfers. The DSP may reconfigure one PLC using the AMBA AHB, while it is processing data with the other PLC.
