AHB Arbiter

Design IP

Overview

SmartDV’s AHB Arbiter IP is a silicon-proven solution that efficiently manages multiple AHB master interfaces competing for bus access in AMBA® AHB-based systems. It supports fixed-priority, round-robin, and user-defined arbitration schemes, ensuring deterministic and conflict-free data transfers. With built-in support for locked transfers and customizable arbitration logic, it offers the flexibility needed for complex SoC designs across automotive, industrial, and consumer applications.

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

Scalable Multi-Master/Slave Architecture – Supports configurable numbers of AHB masters and slaves for flexible SoC integration
Flexible Arbitration Control – Round-robin or priority-based arbitration selectable per slave, enabling system-level optimization
High Throughput with Distributed Arbitration – Arbitration occurs at each slave port, reducing contention and improving overall data throughput
Broad Protocol Support – Handles all AHB protocol transfer types, burst modes, response types, and transfer sizes
Robust Integration Interface – Standardized user interface signals simplify integration with other AHB-compliant IP blocks
Configurable Endianness – Supports both little-endian and big-endian data formats for cross-platform compatibility
Advanced Transfer Handling – Supports locked transfers, early burst termination on error response, and two-cycle error response generation
Slave Response Flexibility – Enables slave-side wait states and programmable response behavior for complex system designs

Compliance and Compatibility

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