Detailed Description

Represents a single memory in the memory hierarchy, consisting of a memory instance and connectivity information.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
		MemoryInstance	memory_instance,
		list[MemoryOperand]	operands,
		dict[MemoryOperand, int]	mem_level_of_operands,
		PortAllocation	port_alloc,
		ServedMemDimensions	served_dimensions,
		OperationalArrayABC	operational_array,
		int	identifier
	)

Initialize the memory level in the hierarchy with the physical memory instance.

Parameters

port_alloc	memory port allocation (physical memory port -> functional memory port)
id	an identifier used for reference check.
