system crash which could cause no ACK frame

received. After retransmitting for several times,

TSoverHTCP will send CPU an interrupt to clear

the current connnection state.

6 TEST AND RESULT

To evaluate TSoverHTCP, it was implemented on

an FPGA using Stratix IV as an FPGA test board.

Table 1 shows the resource utilization of TSover-

HTCP. TSI_FIFO block uses a 4 K-bit inner

RAM to buffer input TS packets and TX_BLOCK

and RX_BLOCK use a 16 K-bit inner RAM to

buffer frames sent and received. TX_BLOCK and

ACK_PARSER cost a lot of resources because

TCP control logic.

The entire TSoverHTCP test environment is

shown in Figure 8. A CPU (LH79520), a ...
