The PCI Encryption/Decryption Controller has various use cases across different industries, including:
always @(posedge clk) begin case(state) IDLE: if(doorbell) state <= FETCH_DESC; FETCH_DESC: begin pcie_mrd_req(desc_addr, 4'd4); // read 32B desc state <= WAIT_DESC; end WAIT_DESC: if(desc_valid) state <= READ_SRC; READ_SRC: begin pcie_mrd_req(src_addr, len); crypto_input <= pcie_rx_data; state <= CRYPTO; end ... endcase end pci encryption decryption controller

A PCI Encryption/Decryption Controller is a hardware or software component designed to manage the encryption and decryption of payment card data. It is a critical element in the payment processing ecosystem, responsible for securing sensitive information such as credit card numbers, expiration dates, and card verification values. // read 32B desc state <
