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.

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
