46 Added operation details to the memory map doc. Memory map should be interpreted with help of ptp_drv_bfm.c. edn_walter 4569d 23h /ha1588/trunk
45 1. optimized area, by removing unused registers.
2. optimized timing, by removing latches.		 edn_walter 4570d 14h /ha1588/trunk
44 Updated TSU testbench. edn_walter 4570d 17h /ha1588/trunk
43 Added software configurable PTP message id mask for TSU parser. edn_walter 4571d 15h /ha1588/trunk
42 Updated RTC testbench. Shrunk 1s to 1us to simulate more cycles during a short time. edn_walter 4571d 21h /ha1588/trunk
41 Added pre-adder to the accumulator to cut down critical timing path. edn_walter 4571d 22h /ha1588/trunk
39 1. Added memory map and feature description.
2. Separated TX RX TSU register addresses.		 edn_walter 4572d 02h /ha1588/trunk
38 1. Redefined the memory map. See changes in reg.v and ptp_drv_bfm.c.
2. Added adj_done signal for CPU polling.
3. Making time_acc_modulo a constant = 256,000,000,000. No need to change it from software side.		 edn_walter 4573d 00h /ha1588/trunk
37 Timestamp format in the queue = null_16bit + timeStamp1s_48bit + timeStamp1ns_32bit + msgId_4bit + ckSum_12bit + seqId_16bit edn_walter 4573d 03h /ha1588/trunk
36 TSU testbench is now self-checking. Test result is reported at end of simulation. edn_walter 4573d 22h /ha1588/trunk
35 Added support for stacked MPLS UDP/IPv4/IPv6 PTP packets. edn_walter 4574d 21h /ha1588/trunk
34 Added LGPL file header to all copyrighted files. edn_walter 4575d 00h /ha1588/trunk
33 Redefined memory map. RTC and TSU now have separate address spans, can be easily divided into to independent modules. edn_walter 4575d 01h /ha1588/trunk
32 Added PTP standard time format output to the top module. Can be connected to external modules. edn_walter 4575d 03h /ha1588/trunk
31 Added hand-shaking for the TSU data reading. edn_walter 4575d 21h /ha1588/trunk
30 Timestamp format in the queue = msgId_4bit + seqId_16bit + null_8bit + timeStamp1s_4bit + null_2bit + timeStamp1ns_30bit edn_walter 4575d 21h /ha1588/trunk
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 4575d 21h /ha1588/trunk
27 Added more bits to the TSU queue information, of which timestamp value is enlarged from 4s to 64s. edn_walter 4576d 03h /ha1588/trunk
26 Updated test case. edn_walter 4577d 22h /ha1588/trunk
25 Updated SOPC Builder component and example system. edn_walter 4578d 21h /ha1588/trunk
