Memory Usage Guide for
Lattice Semiconductor
for LatticeECP/EC Devices
FIFO Reset
A FIFO reset will clear the contents of the FIFO by resetting the read and write pointers as well as put the FIFO
flags in the initial reset state.
Read Pointer Reset
The purpose of the read pointer reset is to indicate retransmit, and is most commonly used in “packetized” commu-
nications. In this application, the user must keep careful track of when a packet is written into or read from the
FIFO.
Register Mode
There are two modes for registering and pipelining the read and write cycles of the memory. In the minimum mode,
a single set of input registers allows synchronous write cycles into the memory array with the other register banks
bypassed. The additional mode includes using the output registers.
Distributed Single Port RAM (Distributed_SPRAM) – PFU Based
PFU-based Distributed Single Port RAM is created using the 4-input LUT (Look-Up Table) available in the PFU.
These LUTs can be cascaded to create larger distributed memory sizes.
Figure 8-15 shows the Distributed Single Port RAM module as generated by the Module Manager.

Data
The generated module makes use of the 4-input LUT available in the PFU. Additional logic like Clock and Reset is
generated by utilizing the resources available in the PFU. The basic Distributed Single Port RAM primitive for the
LatticeECP/EC devices is shown in Figure 8-16.
