In this blog we will review the newest features released as part of the Arm® AMBA® ACE5-Lite protocol, said to improve throughput and meet the low power demands of ever evolving complex multicore SoCs including cache coherency.
The Arm® AMBA® 5 AXI protocol specification supports high-performance, high-frequency system designs for communication between manager and subordinate components. AMBA AXI5 protocols extend prior specification generations and add several important performance and scalability features which closely align these protocols to Arm AMBA CHI. Let’s look at some of the features of the AXI5 protocol in detail.
Arm recently announced the availability of the next iteration of the Arm® AMBA® 5 CHI protocol – CHI Issue F (CHI-F). AMBA 5 CHI-F is built on top of the existing AMBA CHI Issue E (CHI-E) specification (read our blog on AMBA CHI-E here), and introduces several exciting features related to the latest Arm architecture and optimized transaction flows.
Coherent Hub Interface, popularly known as CHI, is an Interface specification that is part of 5th generation of AMBA® protocols (AMBA® 5) from Arm, released in 2013. AMBA® 5 CHI defines the interfaces for connection of fully coherent processors and dynamic memory controllers, to high performance non-blocking interconnects.
SoC designs are growing more complex, not just by the sheer number of transistors that can be packed into one design, but the emergence of different interconnect methods you must use to connect chip internals and to connect to the outside world. Becoming an expert on each of the interconnect protocols is not going to shorten the verification schedules, reduce design productivity and expose design bugs that might only be found when used by the end consumer.
Synopsys offers a broad set of verification solutions for next-generation AMBA® protocols, including AMBA CXS. Synopsys also has verification automation solutions for Arm-based protocols including VC AutoTestbench for testbench generation and VC AutoPerformance for performance verification.
Synopsys offers a broad set of verification solutions for next generation Arm® AMBA® protocols, including AMBA5 CHI Issue D(CHI-D), and verification automation solutions including VC AutoTestbench for Testbench Generation and VC Autoperformance for Performance Verification of ARM based protocols, which designers have widely adopted and achieved numerous tape-out successes. We continue the rapid expansion of Synopsys’ verification solutions for AMBA protocols and strengthen our leadership with our latest offering of VIP for AMBA ACE5 and AXI5, which are already in use by early adopters of the new specifications. Synopsys VIP for the AMBA5 CHI Issue D (CHI-D) specification enabled early customers and partners to extend the standard architecture for their next-generation coherent designs with new enhancements for increased performance. Let’s dive down to understand more about the new features and latency optimization techniques available in AMBA5 CHI Issue D.
Arm TechCon was successfully held at San Jose Convention Center on 8-10th October, 2019. Synopsys protocol experts were there demonstrating our verification solutions for attendees from a wide spectrum of markets like IoT, mobile, automotive, and consumer.
