APB to AHB Bridge

Design IP

Overview

SmartDV’s APB to AHB Bridge IP enables seamless communication between low-bandwidth peripheral devices on the APB (Advanced Peripheral Bus) and high-performance system components on the AHB (Advanced High-performance Bus). It ensures efficient protocol conversion, maintaining data integrity and minimizing latency across bus domains, ideal for SoC designs requiring a reliable interface between control and high-speed data paths.
Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance.

Benefits

Protocol Translation Made Easy – Translates AMBA APB transactions into AHB transactions for seamless SoC connectivity
Asynchronous Domain Bridging – Interfaces two fully asynchronous clock domains between APB and AHB without data loss
Flexible Clocking – Supports any ratio of APB to AHB clock frequencies for integration flexibility
Configurable Architecture – Supports parameterization of:
- APB data bus width and endianness
- AHB data and address bus widths (independent of APB)
- Number of AHB slave interfaces
- Per-slave data width, base address, and address space
- Transfer response (HRESP) signal usage per slave
Compact and Efficient – Low gate count design optimized for area-sensitive applications
Robust Transaction Handling – Ensures reliable handshaking and data integrity across interfaces
