SOCs are everywhere
System-On-Chip (SOC)
URAT
DMA
CPU
Sub CPU
DA
TIME
ROM RAM
AD
To reduce the development period and satisfy
rapidly change of market, Intellectual
Properties (IPs) are used.

IP based SOC market becomes considerable market
on industrial world.
Naturally, the IP venders protect their products
by license and loyalty, to get large income.
In contrast,
There is the concept of Open Hardware 1.

Open Hardware
By releasing Soft IP without any limitation, it
may be refined and enhanced greatly by users in
the world as well as GNU software (linux, gcc and
so on).
Consequently, you can use it as a Zero-Price Part
with high reliability.
Respecting open hardware concept, we provide two
free soft processor cores.
As for design, we thought that it is most
important that you can easily customize and
attach them to your SOC.
