RAM Usage - 4.1 English

The weights, bias, and intermediate feature maps are buffered in the on-chip memory. The on-chip memory consists of RAM which can be instantiated as block RAM and UltraRAM. The RAM Usage option determines the total amount of on-chip memory used in different DPUCZDX8G architectures, and the setting is for all the DPUCZDX8G cores in the DPUCZDX8G IP. High RAM Usage means that the on-chip memory block will be larger, allowing the DPUCZDX8G more flexibility in handling the intermediate data. High RAM Usage implies higher performance in each DPUCZDX8G core. The number of BRAM36K blocks used in different architectures for low and high RAM Usage is illustrated in the following table.
