Notes to Table 4–1:
(1) In addition to device resource usage, Stratix IV device packages also determine the optimal HardCopy IV device mapping path. For example,
the EP4SE360 device comes in H780 and F1152 packages. The mapping paths for the H780 and F1152 packages are the HC4E25 and HC4E35
devices, respectively.
(2) HardCopy IV devices do not have dedicated MLAB blocks but can support the same Stratix IV MLAB functionality. The number of MLABs that
are supported in HardCopy IV devices varies depending on resource usage and the Stratix IV device-to-HardCopy IV device mapping path.
With regards to functionality, memory in HardCopy IV devices and Stratix IV devices
is identical. The memory blocks can implement various types of memory with or
without parity, including true dual-port, simple dual-port, and single-port RAM,
ROM, and FIFO. Table 4–2 lists the size and features of the different memory blocks.
In addition, unused memory blocks in HardCopy IV devices are powered down,
allowing the HardCopy IV devices to have significant power savings.
