Hi Friends,

I got stuck where to start with ..

I ve a input file like below. where I want to compare write data with my read data .. The problem is that the read data should be compared with the lastest write data on that address.

Note- Both write data & read data are in the same file.
TXADDR & TXDATA means -write
RXADDR & RXDATA means - read

Code:

 120 : TXADDR  : 00000000

means at time 120 I am sending a TXADDR -00000000 & the data to be written are like below

Code:

     240 : TXDATA  0000000000000001
     280 : TXDATA  0000000000000002
     320 : TXDATA  0000000000000003
     360 : TXDATA  0000000000000004
     400 : TXDATA  0000000000000005

next when

Code:

 1042 : RXADDR  : 00000000

comes It the time to read from that address 00000000 returns me the data what is written before i.e, the last one..

INPUT FILE

Code:

     120 : TXADDR  : 00000000
     240 : TXDATA  0000000000000001
     280 : TXDATA  0000000000000002
     320 : TXDATA  0000000000000003
     360 : TXDATA  0000000000000004
     400 : TXDATA  0000000000000005
    1042 : RXADDR  : 00000000
    1080 : TXADDR  : 00000020
    1200 : TXDATA  0000000000000011
    1240 : TXDATA  0000000000000012
    1280 : TXDATA  0000000000000013
    1320 : TXDATA  0000000000000014
    1321 : RXDATA  0000000000000001
    1360 : TXDATA  0000000000000015
    1361 : RXDATA  0000000000000002
    1401 : RXDATA  0000000000000003
    1441 : RXDATA  0000000000000004
    1481 : RXDATA  0000000000000005
    1880 : TXADDR  : 00000040
    2000 : TXDATA  0000000000000021
    2040 : TXDATA  0000000000000022
    2080 : TXDATA  0000000000000023
    2120 : TXDATA  0000000000000024
    2120 : TXDATA  0000000000000025
