The following diagram shows the architecture of the Ethernet driver
design in the NDK 2.0 Support Package (NSP).
Generic EMAC/MDIO Chip Support
This new NSP Ethernet driver architecture consists of the following
components:
❏ NIMU-specific layer, which acts as the interface between the NDK
stack and the Ethernet driver. See Section 1.2.1.
❏ Ethernet mini-driver, which manages the EMAC configuration
using the CSL. Also manages DSP interrupts and memory allocation
for packet buffers in
Abstraction Layer (
❏ Generic EMAC/MDIO Chip Support Library (CSL), which contains
the generic APIs and data structures needed to control and configure
EMAC/MDIO peripherals. Also manages buffer descriptors and
interrupt service routines. See Section 1.2.3.
