Applied Signal Processing’s Secure Digital, Compact Flash and Hard Drive Interface (SD/CF/HD)
Framework for Texas Instruments DSPs allows developers to quickly and easily
add Compact Flash or Hard Drive media to TI DSP based hardware. The
Framework includes a Hardware Reference Design, IDE or SD Device Drivers and a
FAT32 compatible File System all of which can be quickly integrated into
your DSP application, saving several man-months of internal development
RAPID PROTOTYPING ENVIRONMENT
A companion product to the SD/CF/HD framework is our Mass Storage Daughter Card. The Mass Storage Daughter Card compliments the Texas Instruments DSKs and Code Composer StudioTM environment to provide developers with a rapid prototyping tool for your DSP applications. Using the Daughter Card and SD/CF/HD Framework, developers can add a robust file system to your application in a matter of hours. This combination allows application software development to continue before your custom hardware is fabricated, compressing your project’s timelines and greatly reducing project risk.

Data Rate Capabilities
Our FAT SD/CF/HD Framework supports data rates up to 4Mbytes/sec for Compact Flash, 9Mbytes/sec for a Hard Drive, and 1MByte/sec for SD. As a reference, below are data rates required for various uncompressed audio streams. The Framework can support all of these raw data rates with either type media.
The file system is available with either a polling or interrupt-based IDE driver. The interrupt-based driver requires 10-40 MIPS to achieve maximum data rates. MIPS depend on the DSP platform, media, and read or write operations.
TMS320C55x, TMS320C64x, TMS320C67x, TMS320DM642, and TMS320C28x DSP families.
Other platforms will be available soon! Please contact us for the latest

Proven Flexible Design
Our SD/CF/HD Framework has been used by our customers in several products including one application which records weeks of audio data to directly to Hard Disk. The SD/CF/HD Framework is a useful component for applications that need features such as audio streaming, data acquisition, or a flexible system reconfiguration options. Applied Signal Processing can provide application development, device driver support, and customization options to exactly match your needs, making sure your application is a success!
