1) Platforms : add new organization for test
2) Load_Store_Unit : add array to count nb_check in store_queue
3) Issue_queue and Core_Glue : rewrite the issue network
4) Special_Register_Unit : add reset value to register CID
5) Softwares : add multicontext test
6) Softwares : add SPECINT
7) Softwares : add MiBench?
7) Read_queue : inhib access for r0
8) Change Core_Glue (network) - dont yet support priority and load balancing scheme

4** bitstring(): print bit pattern of bytes formatted to string.
5**
6** By J. Blauth, Sept. 1992. Hereby placed into the public domain.
7**
8** byze:    value to transform to bitstring.
9** biz:     count of bits to be shown (counted from lowest bit, can be any
10**          even or odd number).
11** strwid:  total width the string shall have. Since between every 4 bits a
12**          blank (0x20) is inserted (not added after lowest bit), width of
13**          bitformat only is (biz+(biz/4-1)). Bits are printed right aligned,
14**          positions from highest bit to start of string filled with blanks.
15**          If value of strwid smaller than space needed to print all bits,
16**          strwid is ignored (e.g.:
17**                bitstr(s,b,16,5) results in 19 chars +'\0').
18**
19**   EXAMPLE:
20**   for (j = 1; j <= 16; j++) { bitstring(s, j, j, 16); puts(s); }
21**       1:                1
22**       2:               10
23**       3:              011
24**       d: 0 0000 0000 1101
25**       e: 00 0000 0000 1110
26**       f: 000 0000 0000 1111
