DSP387

Many data-logging, DSP applications need to save considerable amount of real-time data on hard disks. Sometimes the amount of data exceeds the PCI bandwidth and hence cannot be transferred to host for logging purposes or it is an embedded system with no host system to take care of this requirement. SMT387 is a DSP module with the capability of working with other Sundance modules and capable of writing/reading data to/from two hard disks simultaneously. The SMT387 has support for the latest generation of Serial ATA controller, and comes with a 600MHz DSP and a Virtex-II Pro FPGA. SMT387 will work in an array of module as a slave or as a host and can also run Stand-Alone and use the on-Module flash for booting and control of the Disk Array.

The SMT6087-FS is a software package that allows 3L Diamond applications running on an SMT387 module have access to files on attached SATA disk drives. The package uses the industry standard FAT32 file system so that data can be exchanged with Windows computers running Windows 2000 or Windows XP simply by detaching the drive and plugging it into a spare SATA port on the Windows computer. �DSP application can have a whole host of features like reading directories, deleting files, reading files, creating files etc.

There is also a software (distributed in source format) allowing applications to read and write from the disks from a host program and to transfer dsik content to the host. Please see: Board Support package (SMT6087)

Benifits

• Build low cost real time data acquisition systems using commercial Serial ATA drives, like the Western Digital 'Raptor'
• Function library simplifies application development
• Double buffered memory architecture enables maximum sustained bandwidth
• Independent communications and Serial ATA processors maximize system throughput.
• Max transfer rate is 150Mbytes/sec., whereas the sustained data-rate is limited to approx. 40Mbytes, due to disk performance. (50MB/s at sector 0 reducing linearly to 30MB/s at sector 0x1FFFFFFF)
• High-speed data storage for TIM based parallel DSP systems
• Real-time logging and buffering of data
• FAT32 support and tool for transferring data from disks to host
