Request Negotiation

p_wr_ptr

from user logic to block-of-data rd/wr module

PKT_MEM_PTR_WIDTH

the start address of DRAM for transfer. Each unit is 16-byte piece

Request Negotiation

p_wr_ack

from block-of-data rd/wr module to user logic

1

1=the arbiter acknowledges that the write requester can proceed, 0=otherwise

Data Transfer

p_wr_data_vld

from user logic to block-of-data rd/wr module

1

1=the write data is valid, 0=otherwise

Data Transfer

p_wr_data

from user logic to block-of-data rd/wr module

PKT_DATA_WIDTH

the data transferred from user logic to DRAM

Data Transfer

p_wr_full

from block-of-data rd/wr module to user logic

1

1=notify the user logic to pause transfer the next clock cycle until this signal is deasserted, 0=otherwise

Data Transfer

p_wr_done

from block-of-data rd/wr module to user logic

1

1=this is the last write and no more write will be accepted for this block-of-data, 0=otherwise

Request Negotiation

p_rd_ack

from block-of-data rd/wr module to user logic

1

1=the arbiter acknowledges that the read requester can proceed, 0=otherwise

Data Transfer

p_rd_rdy

from block-of-data rd/wr module to user logic

1

1=block-of-data rd/wr module has data for user logic to read, 0=otherwise

Data Transfer

p_rd_en

from user logic to block-of-data rd/wr module

1

1=user logic reads out one word of data from the block-of-data rd/wr module, 0=otherwise

Data Transfer
