Direct COF Compression
Each branch COF is stored to the trace buffer as a single bit (0=branch not taken, 1=branch taken) until an
indirect COF (indexed jump, return, or interrupt) occurs. The branch COF entries are stored in the byte
fields labelled “Direct” in
. These entries start at byte1[0] and continue through to byte4[7], or
until an indirect COF occurs, whichever occurs sooner. The entries use a format whereby the left most
asserted bit is always the stop bit, which indicates that the bit to its right is the first direct COF and byte1[0]
is the last COF that occurred before the indirect COF. This is shown in
, whereby the Bytes 4 to
1 of the trace buffer are shown for 3 different cases. The stop bit field for each line is shaded.
In line0, the left most asserted bit is Byte4[7]. This indicates that all remaining 31 bits in the 4-byte field
contain valid direct COF information, whereby each 1 represents branch taken and each 0 represents
branch not taken. The stop bit of line1 indicates that all 30 bits to it’s right are valid, after the 30th direct
COF entry, an indirect COF occurred, that is stored in bytes 7 to 5. In this case the bit to the left of the stop
bit is redundant. Line2 indicates that an indirect COF occurred after 8 direct COF entries. The indirect
COF address is stored in bytes 7 to 5. All bits to the left of the stop bit are redundant.
