Fully Enumerated Filter
Filter Description
This section describes how the fully enumerated CoreFIR filter implements hardware (HW) architectures. All
the architectures realize EQ 1 on page 5.
Transposed Architecture
Figure 6 depicts the transposed HW structure. The architecture is functionally equivalent to the structure
shown in Figure 1 , but eliminates the need for a multi-input adder. Instead, it uses the pipelined two-input
adder chain, which makes it highly beneficial for the HW implementation. It also offers low latency
implementation.

Systolic Architecture
The systolic architecture adds more pipelines to the Direct Form I structure of Figure 1 . Depending on
particular filter parameters, the systolic structure can offer better performance due to extensive pipelining.
The structure is always used to implement FIR filters with symmetric impulse response. The systolic
architecture is shown in Figure 7.
