With Virtex-6 there are more hard IP blocks. Hardened solutions are more efficient than any soft solution, allowing faster performance and lower power. Additionally, the hardened technology allows customers to use smaller size devices, hence allowing lower costs solutions. At the same time, hardening blocks that are not required use up precious resources. AMD has carefully chosen the right blocks to integrate, delivering benefits to users and maintaining flexibility. These hardened blocks are thoroughly documented, verified, and offer guaranteed performance, leading to lower risk and shorter design time. FPGAs are truly becoming a system-on-a-chip.
