Table 4-2: ALTERA_FP_ACC_CUSTOM Input Ports

Port Name Required Description

clk Yes All input signals, otherwise explicitly stated, must be synchronous to

this clock

areset Yes Asynchronous active-high reset. Deassert this signal synchronously to

the input clock to avoid metastability issues.

en No Global enable signal. This port is optional.

x Yes Data input port.

n Yes Boolean port which signals the beginning of a new data set to be

accumulated. This should go high together with the first element in the

new data set and should go low the next cycle. The data sets may be of

variable length and a new data set may be started at any time. The

accumulation result for an input will be available after the reported

latency.
