Altera MAX 10 Embedded Memory - Manual (Page 70)

Signal Required Description
sload_data
No Synchronous load data input port. Signal that specifies new multiplication
operation and cancels any existing multiplication operation. If the
MAX_
CLOCK_CYCLES_PER_RESULT
parameter has a value of
1
, the
sload_data
input port is ignored.
Table 10-2: ALTMEMMULT IP Core Output Signals
Signal Required Description
result[]
Yes Multiplier output port. The size of the input port depends on the
WIDTH_R
parameter value.
result_valid
Yes Indicates when the output is the valid result of a complete multiplication.
If the
MAX_CLOCK_CYCLES_PER_RESULT
parameter has a value of
1
, the
result_valid
output port is not used.
load_done
No Indicates when the new coefficient has finished loading. The
load_don
e
signal asserts when a new coefficient has finished loading. Unless the
load_done
signal is high, no other coefficient value can be loaded into the
memory.
