Designers can use the FLEX 10K embedded array for specialized logic functions as well as high-
performance, on-chip memory functions. Complex functions implemented in embedded array blocks
(EABs) consume fewer device resources and operate faster than functions implemented in logic
cells. Because FPGAs are based on logic cells only, FPGA designers must bit-slice and partition
complex or high fan-in functions into multiple logic cells. Consequently, the implementation of
certain logic functions in an FPGA consumes excessive silicon resources and can incur multiple
levels of delays, affecting overall system performance. In contrast, the FLEX 10K architecture, with
its embedded array and logic array, improves the performance and efficiency of complex logic func-
tions such as multipliers.

EABs Allow Elegant Multiplier Implementation
Multipliers, one of the most common functions in digital designs, benefit dramatically from an
architecture that contains both an embedded and a logic array. The following example shows the
efficiency and performance advantages of the Altera FLEX 10K architecture (EPF10K50-4) relative
to the Xilinx XC4000E FPGA architecture (XC4025E-3).
