General Description
Along with CoreAHB2APB, the CoreAPB component
provides an AMBA APB fabric that supports up to 16 APB
slaves. CoreAHB2APB provides APB address decoding in
the form of select signals. CoreAPB is concerned with
multiplexing the read data busses from all the APB slaves
into one single read data bus to send to CoreAHB2APB.
Figure 1 gives an illustration of CoreAPB.

Resource Requirements
The utilization for CoreAPB in a ProASIC3 device is 125 tiles.
Ordering Information
CoreAPB is included in the SysBASIC core bundle supplied with the Actel CoreConsole IP Deployment Platform (IDP).
The obfuscated RTL version of SysBASIC (SysBASIC-OC) is available for free with CoreConsole. The source RTL version of
SysBASIC (SysBASIC-RM) can be ordered through your local Actel sales representative. CoreAPB cannot be ordered
separately from the SysBASIC core bundle.

Datasheet Categories
In order to provide the latest information to designers, some datasheets are published before data has been fully
characterized. Datasheets are designated as "Product Brief," "Advanced," and "Production." The definitions of these
categories are as follows:
Product Brief
The product brief is a summarized version of an advanced or production datasheet containing general product
information. This brief summarizes specific device and family information for unreleased products.
Advanced
This datasheet version contains initial estimated information based on simulation, other products, devices, or speed
grades. This information can be used as estimates, but not for production.
Unmarked (production)
This datasheet version contains information that is considered to be final.
