PCI Express –AMBA AHB Bridge
The GDA PCI Express*-AMBA AHB Bridge is a highly flexible and configurable IP with the PCI Express interface on one side and an AMBA sub system on the other side. The Bridge has been architectured to interface with a PCI Express controller used as an end-point or root-complex devices. The IP uses high speed multi-channel DMA controllers to match the bandwidth requirements of a PCIe Gen2 solution. The design supports AHB PIO, PCI Express PIO, and Write DMA and read DMA types of transfers.
Superior Architecture
The GDA PCI Express-AMBA AHB Bridge is a simple, configurable and layered architecture which is independent of applications, implementation tools or target technology. The controller architecture is carefully tailored to optimize latency, power consumption, and silicon footprint, making it ideal for cost and performance sensitive applications. The solution provides highly scalable bandwidth through a configurable data path width and clock frequency, thus allowing for a highly optimized solution applicable in a wide range of applications.
Most Thoroughly Verified and Interoperable Design
The GDA PCI Express - AMBA AHB Bridge is an exhaustively verified solution and is fully tested against design specific and protocol compliance checklist. The comprehensive random tests ensure a very high coverage. The IP is verified with leading AHB verification IP’s and the verification environment can be configured to run with all the major simulators. The reusable block level verification environment and the formal verification methodology enhance the quality of verification process and add more confidence to the design verification.
The GDA PCI Express-AMBA AHB Bridge solution leverages years of experience in creating IP for Ethernet, RapidIO and PCI Express technologies. The expertise in creating system validated solutions with RTL, synthesis, Simulation, board and software elements ensures delivery of lower risk, compliant and interoperable solution.
Ease of Integration
The GDA PCI Express- AMBA Bridge design is fully synchronous and adheres to standard synthesis, test insertion and physical design practices. The solution allows licensees to easily migrate among COT, FPGA, Gate array, Structured ASIC and Standard cell technologies. The IP with its flexible user logic interface can be easily integrated into a wide range of applications.
Design Configurability
The design offers enormous hardware and software configurable options allowing the user to choose the optimal solution to meet his requirement. The configuration options include
* PIO, DMA or mixed mode of operation
* Up to 8 Read and Write DMA supported
* Maximum Number of PCI Express capable AHB Slave PIO devices supported (0 - 15)
