In the context of ESP8266, what do the letters 'ets' stand for?

[DarioGHub]

The letters 'ets' are used throughout the firmware, SDK and esp8266/Arduino code.

1. first letters in the boot message:

 ets Jan  8 2013,rst cause:2, boot mode:(3,7)

2. numerous define and function identifiers. Just search the esp8266/Arduino distribution.

#define os_delay_us ets_delay_us
ets_printf_P(const char *str, ...)

3. filenames:

#include "ets_sys.h"

Tried Google, but nothing, excepting online dictionaries with hundreds of possibilities.
Also scoured ~10 Espressif PDFs.

Is it an acronym for Espressif Tensilica System?
Pedantic perhaps, but I'd like to know. A reference would be over the top.

Based on this comment I think its safe to assume it stands for "Espressif Task Scheduler".

[DarioGHub]

Agreed. Thanks soon much for digging that reference out of the source.
