RecMII

maximum cycle’s length in all cycle length 

cycle length:
sum latencies of ops in the cycle

What is the difference between an EQ-model and an LEQ-model VLIW?

• Equals (EQ) Model: Each operation takes exactly its specified
latency. Register values don’t change until operation completes.
– Reduces register pressure because source operands stay
around longer.
– Can’t reduce operation latencies and maintain source code
compatibility.
• Less-Than-or-Equals (LEQ): Operations may take up to their
specified latency
– Destination register contents become unreliable immediately
– Simplifies implementation of precise interrupts
– Can reduce operation latencies and maintain source code
compatibility
