• i have a question about AXI BUS.
    Um,,,, I send 32-bit data to slave. 0 to 3 bits are meaningless data. If so, I should send the original strobe signal to 4'b1110. If I send a strobe signal to 4'b1111, is this a violation of...
  • why PSTRB signal in APB4 have four bits?
    PSTRB signal indicates which byte lanes to update during a write transfer. it shows that the bus contain valid data, when PSTRB[3:0]=1111. why we need bus instead of single bit PSTRB signal?
