Nios II CRC Acceleration Example Design v2.2.0 readme.txt This file contains the following sections: o Package Contents o Tool Requirements o Project Directory Names o Release History o Important Notice o Contacting Altera Package Contents ================ CRC Reference Design v2.2.0 Tool Requirements ================= This reference design requires the following: - Quartus II software version 7.2 or later - Nios II Embedded Design Suite version 7.2 or later - IP Design Suite version 7.2 or later - Modelsim-Altera tool version 6.1g or later (if you wish to simulate the design) Please contact your local sales representative if you do not have one of these software tools. Project Directory Names ======================= When you extra the archive the following folder structure will be created: |--- |--- |--- |--- |--- |--- |--- |--- Release History =============== Version 1.0.0 ------------- Initial release Version 2.0.0 ------------- Updated release using Nios II and a new CRC Component Version 2.1.0 ------------- Updated the system and components using SOPC Builder 7.2 and Component Editor (new flow) Version 2.2.0 ------------- Removed the CRC Custom instruction as it will be included with the Nios II Custom Instruction User Guide. Important Notice ================ In the Cyclone II design, a pipelined bridge is added between the DMA read master and the SSRAM to artifically increase the memory latency. This change is to overcome the latency within the DMA that causes the throughput in the provided design to degrade. With this change the DMA is capable of reading from the SSRAM and writing to the CRC component every clock cycle. The Stratix II design is not affected by this issue since the SSRAM contains an extra cycle of latency since it operates at 166MHz. Contacting Altera ================= Although we have made every effort to ensure that this version of the CRC reference design works correctly, there may be problems that we have not encountered. If you have a question or problem that is not answered by the information provided in this readme file, please contact your Altera Field Applications Engineer. If you have additional questions that are not answered in the documentation provided with this design, contact Altera Applications using one of the following methods: Technical Support Hotline: (800) 800-EPLD (U.S.) (408) 544-7000 (Internationally) World wide web: http://www.altera.com/mysupport Last updated June, 2006 Copyright 2006 Altera Corporation.
