Supplied in SysBASIC Core Bundle Up to 16 APB Slave Devices Supported Automatic Connection to AHB Bridge (CoreAHB2APB) and APB Slaves Benefits • • • Allows Easy Connection of APB Devices to a CoreMP7 or Cortex-M1 Subsystem Auto Stitch in CoreConsole for Rapid Development Compatible with Advanced Microcontroller Bus Architecture (AMBA), CoreMP7, and Cortex-M1 1 2 2 2 3 3 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. Supported Device Families • • • • • • Compliant with AMBA Contents Key Features • • • Supported in the Actel Libero® Integrated Design Environment (IDE) Fusion IGLOO™ IGLOOe ProASIC®3L ProASIC3 ProASIC3E There is one APB master interface, which is typically connected to the AMBA Bridge, and 16 equal-sized (16 MB) APB slave interfaces.

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. 2 v2.1 CoreAPB List of Changes The following table lists critical changes that were made in the current version of the document. Previous Version Changes in Current Version (v 2 .1 ) v2.0 Advanced v0.1 Page The "Supported Device Families" section was updated to include ProASIC3L. 1 The "Resource Requirements" section was updated to change ProASIC3E to ProASIC3. 2 The "Product Summary" section was updated to include Cortex-M1 and IGLOO/e information. 1 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. v2.1 3 Actel and the Actel logo are registered trademarks of Actel Corporation.
