QDR II SRAM
Interfacing to the UPL block, CoSine includes a dedicated QDR
controller with 32MB of QDR II SRAM memory. Especially applicable to
fixed point operations, QDR offers the unique characteristic of
simultaneous read/write operations.For many
DSP functions, available block RAM within the Virtex-II Pro 2VP70 is
sufficient. But for requirements that exceed the available internal
block RAM, the 32MB of QDR is a high speed, powerful resource for
multiply/accumulate functions and rapid parallel processing.
The memory can be used by the UPL for FIFO's,
corner turning memory, coefficient storage, or other, implementation
dependent uses.
An optional QDR parity module is offered outside
of the QDR controller for greater flexibility. |
