What is your preferred platform for FPGA Design Flow ?:


IP Vendor: 
El Camino, GmbH
IP Target Vendor: 
IP Type: 
IP Category: 
Bus Interface and IO
IP Supported FPGA Device: 
Cyclone II
Stratix II
IP Description: 

Supports MultiMedia Card (MMC) and Secure Digital (SD) card in serial peripheral interface (SPI) mode
Variable data rate up to 20 Mbps
Hardware assisted cyclic redundancy check (CRC) calculation
Low-level hardware abstraction layer (HAL) drivers included
Windows utility for raw data read/write access on PC platform
Includes prototyping adapter for Altera® and El Camino Nios® II development boards
Optional file allocation tables FAT12/FAT16 stand-alone Nios II file system

The SD/MMC SPI core with Altera Avalon® bus interface allows the designer to easily connect SOPC Builder systems to standard MMC and SD card flash-based memory devices. The MMC and SD cards are universal, low-cost data storage and communication media widely used in consumer products such as digital cameras and cellular phones. The SD/MMC SPI core is fully compliant with SOPC Builder and integrates easily into any SOPC Builder-generated system.

For the Nios II processor, El Camino provides low-level driver routines for the SD/MMC SPI core. The drivers provide universal access routines for MMC and SD memory devices, eliminating the need for additional low-level code to read or write raw data from or to the SD/MMC cards."
