AXI to APB Bridge IP
Design IP
Overview

SmartDV’s AXI to APB Bridge IP enables seamless communication between high-performance AXI-based systems and simpler, lower-power APB peripherals. It ensures efficient protocol conversion, allowing integration of a wide range of peripheral devices into AXI-based SoC designs with minimal latency and high reliability.

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. It is ideal for applications where system control and status registers are mapped to APB slaves, simplifying system design without compromising on performance.

Benefits
  • Seamless Protocol Bridging – Enables smooth translation between high-performance AXI and low-power APB interfaces for effective system-level integration
  • Broad Compatibility – Supports AXI3, AXI4, and AXI4-Lite on the master side and APB3/APB4 on the slave side
  • Configurable Interface Parameters – Allows customization of endianness and data width for both AXI and APB interfaces
  • Error Handling Support – Includes a Data Phase timeout mechanism to generate error responses if no acknowledgment is received from the APB side
  • Orderly Transaction Management – Accepts simultaneous read/write requests from AXI and serializes them for correct execution on APB
  • Compact and Resource-Efficient Design – Optimized for minimal area usage while maintaining protocol compliance and performance
  • Ideal for Peripheral Access – Best suited for connecting slower control/status peripherals to high-speed AXI-based SoCs
