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
