|

|

ESP8285 is like ESP8266 + 1MB flash, but its internal I/O connection from CPU
|
||||
core to flash is DIO not QIO, which makes it read flash data slower.
|
||||
So the function will speed up ESP8285 obviously.
|
||||
|
||||
The calculation uses "ibus_data" to speed up load data from instruction bus.
|
||||
|
||||
Disabling the "assert" function at menuconfig can speed up the calculation.
