32 Added PTP standard time format output to the top module. Can be connected to external modules. edn_walter 4458d 04h /ha1588/trunk/rtl/tsu/tsu.v
29 Added multicycle timing constraint to ptp_parser.v, which works at data rate of (32bit * 4 gmii_clk cycle). Fmax can exceed 250MHz. edn_walter 4458d 21h /ha1588/trunk/rtl/tsu/tsu.v
27 Added more bits to the TSU queue information, of which timestamp value is enlarged from 4s to 64s. edn_walter 4459d 04h /ha1588/trunk/rtl/tsu/tsu.v
18 Added QuartusII Place and Route project for top level ha1588.v edn_walter 4467d 22h /ha1588/trunk/rtl/tsu/tsu.v
15 Renamed module name for tsu and rtc.
Added folder for reg and top.
Added folder for sopc, preparing for Altera SOPC Builder customized component.		 edn_walter 4474d 17h /ha1588/trunk/rtl/tsu/tsu.v
10 Added parser support for L2_PTP and IPv4_UDP_PTP frame formats. edn_walter 4480d 17h /ha1588/trunk/rtl/tsu/tsu_queue.v
9 Timestamp format in the queue = seqId_16bit + msgId_4bit + timeStamp1s_2bit + timeStamp1ns_30bit edn_walter 4481d 17h /ha1588/trunk/rtl/tsu/tsu_queue.v
8 Timestamp format in the queue = seqId_16bit + msgId_2bit + timeStamp_30bit edn_walter 4481d 23h /ha1588/trunk/rtl/tsu/tsu_queue.v
7 Reduced the timestamp length from 80b to 30b to save memory, since the software could be fast enough to handle timestamp rollover events per 1s. Enlarged the fifo depth to 15, to accomodate 10 ptp sync messages per 1s. edn_walter 4482d 00h /ha1588/trunk/rtl/tsu/tsu_queue.v
5 Added dcfifo to store ptp time stamps. ash_riple 4484d 16h /ha1588/trunk/rtl/tsu/tsu_queue.v
4 Added source code and unit test for TSU. ash_riple 4485d 16h /ha1588/trunk/rtl/tsu/tsu_queue.v
