Memory Model

This header defines enumerations and type lookups for supporting various memory models for the ETL.

These allow template classes to use optimally sized variables for the model.

For example, if a container will never have more than 256 elements then indexes and counts may be contained in an 8

bit type.

memory_model

A user type that defines values for four different memory models.

MEMORY_MODEL_SMALL

MEMORY_MODEL_MEDIUM

MEMORY_MODEL_LARGE

MEMORY_MODEL_HUGE

Example

etl::memory_model::MEMORY_MODEL_LARGE

____________________________________________________________________________________________________

size_type_lookup

A type lookup template that defines a type that equates to the size type for memory model.

using size_type = typename etl::size_type_lookup<etl::memory_model::MEMORY_MODEL_LARGE>::type;

The defined types are...

MEMORY_MODEL_SMALL uint_least8_t

MEMORY_MODEL_MEDIUM uint_least16_t

MEMORY_MODEL_LARGE uint_least32_t

MEMORY_MODEL_HUGE uint_least64_t
