AR# 54710: MIG 7 系列- DDR3 –控制器在 read-modify-write 操作中挂起。 Description 发现问题的版本MIG 7 系列 1.8解决问题的版本:敬请参见(Xilinx 答复 45195) 用户设计顶层有一个已知的问题,即在 ECC 逻辑启用时,发出的 read-modify-write 操作指令会让控制器冻结。这个问题的故障特征是能正确执行初始读...
DDR2 is fast for burst accesses transfers, but the 'time to first data' for memory reads hasn't really changed much over the last 20 years. A 3.5GHz x86 cpu will only run at anything like that speed when all the code and data is cached. If you are doing occaisional...
The MIG v3.3 Virtex-6 FPGA DDR2/DDR3 designs support Read Modify Write commands. When aread-modify-writeis performed in conjunction with a partial data mask, the modified data is not written to the memory. Solution This is a known issue with MIG v3.3 which affects both simulation and har...
