Support for EZchip development platforms,
|
|
based on ARC700 cores.
|
|
We handle few flavors:
|
|
- Hardware Emulator AKA HE which is FPGA based chassis
|
|
- Simulator based on MetaWare nSIM
|
|
- NPS400 chip based on ASIC

Here we add new hierarchy for CPUs topology.
|
|
We got:
|
|
Core
|
|
Thread
|
|
At the new thread level each CPU represent one HW thread.
|
|
At highest hierarchy each core contain 16 threads,
|
|
any of them seem like CPU from Linux point of view.
|
|
All threads within same core share the execution unit of the
|
|
core and HW scheduler round robin between them.
