AsyncFifo

Instance Constructors

new AsyncFifo(gen: T, entries: Int, enq_clk: Clock, deq_clk: Clock)

gen
the type of data in the fifo
entries
the max number of entries in the fifo. The actual size will be rounded up to the next power of 2 - (size = 1<<log2Up(entries))
enq_clk
clock for the input (writing, queuing) side
deq_clk
clock for the output (reading, dequeuing side) side

Type Members

type neededWireWraps = HashMap[StackTraceElement, ArrayBuffer[Data]]

verifyWireWrap (Chisel3) - verify assignment semantics (type-only nodes must be wire-wrapped)
verifyWireWrap (Chisel3) - verify assignment semantics (type-only nodes must be wire-wrapped)
returns
