Data Memory value dictionary

[FrankWu1998]

Hello, can you tell me how to set the specific value of the position of these question marks.

dataMem_lat_dict = {'256' : 1, '512' : 1, '1024': 1, '2048': 1, '4096': ?, # set '8192': ?}

dataMem_pow_dyn_dict = {'256' : 0.16, '512' : 0.24, '1024': 0.33, '2048': 0.57, '4096': ?, # set '8192': ?}

dataMem_pow_leak_dict = {'256' : 0.044, '512' : 0.078, '1024': 0.147, '2048': 0.33, '4096': ?, # set '8192': ?}

dataMem_area_dict = {'256' : 0.00056, '512' : 0.00108, '1024': 0.00192, '2048': 0.00392, '4096': ?, # set '8192': ?}

dataMem_lat_dict = {'256' : 1, '512' : 1, '1024': 1, '2048': 1, '4096': ?, '8192': ?}

dataMem_pow_dyn_dict = {'256' : 0.16, '512' : 0.24, '1024': 0.33, '2048': 0.57, '4096': ?, '8192': ?}

Hi @FrankWu1998,

The keys that have their values currently are reported using the CACTI tool. In subsequent PR some other keys are included as well.

Thanks, Shubham

@negishubham Thank you very much.

Hello! @negishubham I cannot know the hardware parameters of the memory module other than the size, which makes me unable to directly model the memory module. Can you provide a .cfg file describing eDRAM in CATTI?

best regards, Yifan Wu

Note the read and write lat/pow are for entire xbar

xbar_rd_lat = 328.0 1000 (1/32.0) xbar_wr_lat = 351.0 1000 (1/32.0)

Hello, is the above 32.0 equal to cfg.xbar_ size？ cfg.xbar_size = 32 --> xbar_wr_lat = 351.0 1000 (1/32.0) ? cfg.xbar_size = 128 --> xbar_wr_lat = 351.0 1000 (1/128.0) ?
