July 2010 Preliminary Altera Embedded Systems Development Kit, Cyclone III Edition
10. Developing USB and SD
Card based Systems
The LCD Multimedia HSMC provides SD Card peripheral so you can add
SD Card interface to your system. The H2SUM provides a USB PHY so
you can add USB capability to your Embedded System by adding USB 2.0
PHY IP core. In this section, details regarding the development of SD
Card interface and USB interface are presented.

SD Host Controller IP Core
The SD Host Controller IP Core included in the LCD processor design
example as well as the Application Selector design example uses a third
party vendor, SLS’s 4-Pin SD Card Controller IP Core. This core support
both 1-bit and 4-bit SD mode. The core provided by SLS is an encrypted
SOPC Builder ready IP available for purchase.
