This module change the Atom which contains the program to send the Data

Atom, BitOps;

PCCacheProg: CEDAR PROGRAM

IMPORTS Atom, BitOps

EXPORTS

~ BEGIN

Service Types

QWord: TYPE = ARRAY [0 .. 2) OF CARD;

Service Procs

Q: PROC [c: QWord] RETURNS [rc: REF ANY] = {rc ← NEW[QWord ← c]};

C: PROC [c: CARD] RETURNS [rc: REF ANY] = {rc ← NEW[CARD ← LOOPHOLE[c]]};

B: PROC [c: CARDINAL] RETURNS [rc: REF ANY] = {rc ← NEW[CARDINAL ← c]};

AdDBus: PROC [bd,hyb,Int,ci,pth: CARDINAL 𡤀] RETURNS [ad: CARDINAL 𡤀] ~ {

Address in the DBus is :

<BoardNum:4><HybridNum:4><InterfaceNum:3><ChipNum:2><PathNum:3>

<ChipNum>=0 is for BIC

ad ← BitOps.WShift[bd,12]+BitOps.WShift[hyb,8];

ad ← ad+BitOps.WShift[Int,5]+BitOps.WShift[ci,3]+pth;

};

IdCte: PROC [t,v:CARDINAL] RETURNS [id:CARDINAL] ~ {

The structure of the Identificator is "0101 cccc ccrr rrrr"

cccccc is the Type, rrrrrr is the Version

id ← 5000H + BitOps.WShift[t,6] + v;

};
