When configured as RAM or ROM, you can use an initialization file to pre-load the
memory contents.
M512 RAM blocks can have different clocks on its inputs and outputs. The wren,
datain, and write address registers are all clocked together from one of the two
clocks feeding the block. The read address, rden, and output registers can be clocked
by either of the two clocks driving the block, allowing the RAM block to operate in
read and write or input and output clock modes. Only the output register can be
bypassed. The six labclk signals or local interconnect can drive the inclock,
outclock, wren, rden, and outclr signals. Because of the advanced interconnect
between the LAB and M512 RAM blocks, ALMs can also control the wren and rden
signals and the RAM clock, clock enable, and asynchronous clear signals.
shows the M512 RAM block control signal generation logic.
The RAM blocks in Arria GX devices have local interconnects to allow ALMs and
interconnects to drive into RAM blocks. The M512 RAM block local interconnect is
driven by the R4, C4, and direct link interconnects from adjacent LABs. The M512
RAM blocks can communicate with LABs on either the left or right side through these
row interconnects or with LAB columns on the left or right side with the column
interconnects. The M512 RAM block has up to 16 direct link input connections from
the left adjacent LABs and another 16 from the right adjacent LAB. M512 RAM
outputs can also connect to left and right LABs through direct link interconnect. The
M512 RAM block has equal opportunity for access and performance to and from
LABs on either its left or right side.
