OakDSPCore Architecture
The OakDSPCore consists of three main execution units
operating in parallel:
The Computation/Bit Manipulation Unit (CBU)
The Data Address Arithmetic Unit (DAAU)
The Program Control Unit (PCU)
The OakDSPCore also supports four user-definable regis-
ters, enabling future expansion of the core residing in off-
core glue logic. The user defined registers are part of the
core register set, meaning that they can be accessed by
most OAK instructions.

Note:
X- and Y-RAM sizes depend on the customer
’
s need. The variable size minimizes overhead area.
