AHB Decoder

Design IP

Overview

SmartDV’s AHB Decoder IP core is a silicon-proven solution designed to simplify address decoding and routing within AMBA-based SoC architectures. It enables efficient communication between AHB masters and multiple AHB slaves by accurately decoding address ranges and directing transactions to the appropriate target.

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. This makes it an ideal choice for system designers looking to streamline bus interconnects in a scalable and reliable way.

Benefits

Flexible Master-Slave Configuration – Supports configurable number of AHB masters and slaves to match system architecture needs
Comprehensive Transfer Support – Handles all AHB burst types, burst transfers, response types, and transfer sizes for full protocol coverage
Endian Flexibility – Configurable data bus endianness to align with system requirements
Intelligent Address Decoding – Decoder logic maps incoming addresses from AHB masters to the appropriate slave device on the bus
Integrated Data Routing – Built-in multiplexer logic selects read data from the correct slave and routes it back to the initiating master
Optimized for SoC Interconnects – Simplifies AHB bus arbitration and connectivity, enabling efficient and scalable AMBA-based systems

Compliance and Compatibility

Compliant with AMBA 2, AMBA 3, and AMBA 5 AHB specifications
Compatible with all major EDA synthesis, simulation, and linting flows
