# Core Components
## Overview

The core components are organized into two groups.
The first group (referred to as `G0` from now on) contains `hal`, `xtensa` and `riscv` (referred to as `arch` components from now on), `esp_rom`, `esp_common`, and `soc`. This
group contain information about and low-level access to underlying hardware; or in the case of `esp_common`, hardware-agnostic code and utilities.
These components can depend on each other, but as much as possible have no dependencies outside the group. The reason for this is that, due to the
nature of what these components contain, the likelihood is high that a lot of other components will require these. Ideally, then, the dependency
relationship only goes one way. This makes it easier for these components, as a group, to be usable in another project. One can conceivably implement
a competing SDK to ESP-IDF on top of these components.
The first group (referred to as `G0`) includes `hal`, `arch` (where `arch` is either `riscv` or `xtensa` depending on the chip), `esp_rom`, `esp_common`, and `soc`. This group contains information about and provides low-level access to the underlying hardware. In the case of `esp_common`, it contains hardware-agnostic code and utilities. These components may have dependencies on each other within the group, but outside dependencies should be minimized. The reason for this approach is that these components are fundamental, and many other components may require them. Ideally, the dependency relationship only goes one way, making it easier for this group to be usable in other projects.
The second group (referred to as `G1` from now on) sits at a higher level than the first group. This group contains the components `esp_hw_support`, `esp_system`, `newlib`, `spi_flash`,
`freertos`, `log`, and `heap`. Like the first group, circular dependencies within the group are allowed; and being at a higher level, dependency on the first group
is allowed. These components represent software mechanisms essential to building other components.
The second group (referred to as `G1`) operates at a higher level than the first group. `G1` includes the components `esp_hw_support`, `esp_system`, `newlib`, `spi_flash`, `freertos`, `log`, and `heap`. Like the first group, circular dependencies within this group are allowed, and these components can have dependencies on the first group. G1 components represent essential software mechanisms for building other components.
