Support for ARC development boards, provided by Synopsys.
These are based on FPGA or ISS. e.g.
- ARCAngel4
- ML509
- MetaWare ISS

SMP Extensions to ARC700, in a "simulation only" Model, supported in
ARC ISS (Instruction Set Simulator).
The SMP extensions include:
-IDU (Interrupt Distribution Unit)
-XTL (To enable CPU start/stop/set-PC for another CPU)
It doesn't provide coherent Caches and/or Atomic Ops (LLOCK/SCOND)

IP to add artificial latency to BVCI Bus Based FPGA builds.
The default latency (even worst case) for FPGA is non-realistic
(~10 SDRAM, ~5 SSRAM).

depends on ARC_HAS_BVCI_LAT_UNIT
help
There are multiple Latency Units corresponding to the many
interfaces of the system bus arbiter (both CPU side as well as
the peripheral side).
To add latency to ALL memory transaction, choose Unit 0, otherwise
for finer grainer - interface wise latency, specify a bitmap (1 bit
per unit) of all units. e.g. 1,2,12 will be 0x1003
Unit 0 - System Arb and Mem Controller
Unit 1 - I$ and System Bus
Unit 2 - D$ and System Bus
..
Unit 12 - IDE Disk controller and System Bus
