|
The ESP32 is a dual-core system with two Harvard Architecture Xtensa
|
|
LX6 CPUs. All embedded memory, external memory and peripherals are
|
|
located on the data bus and/or the instruction bus of these CPUs.
|
|
With some minor exceptions the address mapping of two CPUs is
|
|
symmetric, meaning they use the same addresses to access the same
|
|
memory. Multiple peripherals in the system can access embedded
|
|
memory via DMA.
|
|
|
|
The two CPUs are named "PRO_CPU" and "APP_CPU" (for "protocol" and
|
|
"application"), however for most purposes the two CPUs are
|
|
interchangeable.
