APB2APB BRIDGE IIP

Overview

COMPETITIVE ADVANTAGE

The SivaKali Tech APB2APB BRIDGE IIP is a highly reliable, silicon-proven IP core designed for high-performance system integration. Engineered to meet strict industry compliance standards, this core offers exceptional flexibility and ease of integration into both ASIC and FPGA designs. Forming the high-speed communication backbone of complex System-on-Chips. Validated on leading FPGA platforms and foundry nodes, it provides a low-risk, time-to-market advantage for developers.

COMPETITIVE ADVANTAGE

Deadlock Free: Robust routing logic prevents system hang-ups under heavy load conditions.

Low Latency Bridging: Efficient clock domain crossing and protocol conversion with minimal cycle overhead.

High Frequency: Pipelined architecture designed to close timing at high clock frequencies in modern nodes.

Scalable: Easily configurable for simple bus fabrics or complex, multi-layer network-on-chip (NoC) implementations.

FUNCTIONAL DESCRIPTION

CORE: Core module performs all the below functionalities in the APB2APB BRIDGE IIP. Ports of core module are the top level ports for the APB2APB BRIDGE IIP.

APB SLAVE: APB Slave is used to respond to a read or write operation within a given address-space range. It accepts address and control from the master and returns data/response.

APB MASTER: APB Master is use to initiate read and write operations by providing an address and control information.

DATA ALLIGNER: Data Aligner is used to adjust the data positions and size between APB and APB formats.

APB TRANSFER CONTROLLER: It generates and controls APB protocol signals for each transfer.

ADDRESS DECODER: Address Decoder checks the APB address and identifies the corresponding APB slave based on the configured address ranges.
