02:48PM EDT - 50 Gbps config interface

02:48PM EDT - Hardware RoT

02:48PM EDT - SHA3 engine, AES, RSA, AES-key

02:48PM EDT - Programmable logic - 900K LUTs, 2M LC, and 1.8M FLOPs

02:48PM EDT - 4x larger CLB -> 64 flip flops

02:48PM EDT - 158 Mb of URAM and BRAM - 50% lower power than prev gen

02:48PM EDT - Versal Programmable Logic DSP, DSP58

02:48PM EDT - 1958x DSP58 with FP support

02:49PM EDT - 400 AI Engine Tiles, 133 TOPs in INT8

02:49PM EDT - Non-blockign interconnect mesh

02:49PM EDT - 12.5MB L1 distributed memory

02:51PM EDT - In AI engine: 32b Scalar RISC Processor, 2 scalar ops/stream access, 512-bit SIMD vector processor, vec128int8 or vec8fp32, 7+ OPs per cycle VLIW

02:51PM EDT - 128 INT8 MACs per cycle per core

02:51PM EDT - Suited for signal processing workloads

02:52PM EDT - Data movement is done through orchistrated DMA

02:53PM EDT - Memory caches supports multicast/broadcast

02:53PM EDT - Very efficient transmission of streamed data

02:56PM EDT - Versal offers deterministic performance and low latency

02:56PM EDT - Map the compute onto different parts of the ACAP

02:57PM EDT - Software programmable framework

02:58PM EDT - Trying to abstract the programming from hardware into regular C++

02:58PM EDT - Frameworks like mxnet, TensorFlow, Caffee

02:59PM EDT - First Xilinx 7nm device, 133 TOPs, PCIe Gen4 and CCIX

02:59PM EDT - Adaptable heterogeneous system architecture

03:00PM EDT - Q&A

03:00PM EDT - Q: HBM? A: Coming

03:01PM EDT - Q: Support CCIX? Support for Gen-Z and CXL? You're members of those consortiums. A: No official plan on Gen-Z. CXL is still new.

03:01PM EDT - That's a wrap. Next talk is Intel's Spring Crest.

    Martinique car rental only prefer localizes peoples because their branch in France. Martinique car rental agencie are primarily for those people who needs a car for a short period of time. martinique car rental serves these four cars are Dacia Sandero or Kia Picanto, Peugeot 308, BMW x1, and Citroën Jumpy. It mainly located near airports or busy city areas.

    Thailand is known for tropical beaches, grand royal palaces, and ornate temples that display buddha figures. In thailand tour is particularly good for money for families , the humble three-star hotels in Thailand are often of a better standard than four-star accommodation in India. the best places to visit in thailand are Bangkok, Pattaya, Hua Hin Thailand, and Phuket & Krabi, etc.
