The CDM has two 240 pin Samtec connectors and one 60 pin Samtec connector
connecting the CEVA core adapters to the CDM. These connectors provide
the Power, GND, control, address bus, data bus and other signals between
the CDM and the adapters.
The CDM includes an auto detection interface that recognizes the plugged
Core adapter and selects the appropriate interface to that specific core
adapter.
The Core adapter support includes the following interfaces:
- 64-bit data AHB master bus
- 64-bit data AHB slave bus
- 32-bit APB bus
- Control signals
These interfaces allow full connectivity between a CEVA-X core implementation
(either on FPGA or in silicon) and the AHB interconnect matrix implemented
on the Demo Board FPGA.
