Chapter 3: DSP Block Implementation in HardCopy IV Devices
3–3
Conclusion
f For more information about Stratix IV DSP blocks, refer to the DSP Blocks in Stratix IV
Devices chapter in volume 1 of the Stratix IV Device Handbook.
Depending on the Stratix IV DSP configurations, the Quartus II software partitions
the DSP function into a combination of DSP HCell macros for the HardCopy IV
devices. This optimizes the DSP function and allows the core fabric to be used more
efficiently.
Conclusion
HardCopy IV devices use HCells to implement the DSP block functions of Stratix IV
devices. All the Stratix IV DSP operational modes are supported. Implementing DSP
functions using HCells allows the HardCopy IV device core fabric to be used
efficiently and offers significant static power savings compared with Stratix IV
prototype devices.
