The Symmetrical
Array
4
AT40K/AT40KLV Series FPGA
At the heart of the Atmel architecture is a symmetrical array of identical cells,
see Figure 1. The array is continuous from one edge to the other, except for bus repeat-
ers spaced every four cells, see Figure 2 on page 5. At the intersection of each repeater
row and column there is a 32 x 4 RAM block accessible by adjacent buses. The RAM
can be configured as either a single-ported or dual-ported RAM
nous or asynchronous operation.
Note:
