In the AMBA High-performance Bus (AHB) a system bus is used to connect a processor, a DSP, and high-performance memory controllers where as the AMBA Advanced Peripheral Bus (APB) is used to connect (Universal Asynchronous Receiver Transmitter) UART. It also contains a Bridge, which connects the AHB and APB buses.
The AHB to APB bridge is an AHB slave and the only APB master which provides an interface between the highspeed AHB and the low-power APB. Read and write transfers on the AHB are converted into equivalent transfers on the APB.
To design and simulate a synthesizable AHB to APB bridge interface using Verilog and run single read and single write tests using AHB Master and APB Slave testbenches. The bridge unit converts system bus transfers into APB transfers and performs the following functions:
The AHB to APB sync-down bridge, cmsdk_ahb_to_apb.v, has the following features: Supports APB2, APB3, and APB4. Runs the APB interface semi-synchronously slower than the AHB interface.
Jun 5, 2024 · The architecture and implementation of an AHB 2 APB bridge, a standardized bus-to-bus interface that allows interaction among several buses in a System-on-Chip architecture (Vani and Roopa 2010). The AHB 2 APB bridge is designed and tested using Verilog, and its testbench produced positive findings for UVM verification and further testing.
the AHB to APB Bridge has its AHB interface connected to a Slave component port on an AHB Channel module, and its APB interface connected to the Master component port on an APB Channel module. AHB to APB Bus Bridge Features • Translates AMBA® AHB transactions to APB transactions • Low latency • Low Gate Count • Supports APB 2.0 and APB ...
The AHB2APB implements an AMBA® AHB to an AMBA® APB bus bridge, allowing the connection of peripherals with an APB interface to an AHB bus. The highly-configurable core translates read or write AHB bus transactions to APB bus transactions.
The AHB-APB bridge is an AHB Client, providing an interface between the high-speed AHB domain and the low-power APB domain. It is used to provide access to the programmable control registers of peripherals (see Product Mapping).
The Roa Logic AHB-Lite APB4 Bridge is a fully configurable bridge IP to enable AHB-Lite based hosts to communicate with APB4 based peripherals. The core parameters and configuration options are described in this section.
The MSS supports APB peripherals (CAN, MMUART, SPI, I2C) and configuration interfaces to other blocks (DDRC, AXI-SWITCH, ETHERNET) via the AHB-Lite bus generated from S5 of the AXI Switch, S5 is converted to APB using an AHB-to-APB bridge.
