Authors Notes:-

 1) Instructions timings are accurate to within:

                 4 * MCLK
                 --------   
                     i
 
          where 
               i    is the number of instructions tested
               MCLK is the system clock (125 nS on an 8 MHz machine)

    ARM instructions are therfore calculated to within 2 nS +- 2%
 2) ARM Speed in MIPS is calculated as the average number of each
    instruction Group in a test sample of 1000 instructions
 3) IOC and VIDC types remain Unknown at present
 4) Checks are made for all processors known to date. ie. ARM 1,2 and 3
 5) Interrupts and DMA requests are stopped whilst calculations are
    taking place
 6) Looped instructions are calculated as one instruction of the specific
    Group + one Group 1 + one group 4 instruction
 7) Instruction timings are calculated during Video Flyback, and are
    therefore dependant on the Video Flyback period and DRAM refresh
    (large modes with no vertical boarders will affect results)
 8) Group 1a results on ARM 2's do not take account of the hardware bug
    (instructions take 24 S cycles rather than the maximum of 16)
 9) Instruction indexes are relative to a perfect ARM 2 running at 8 MHz
10) FPU instruction speeds are calculated by either 3, 16 or 80
    instructions depending upon the instruction in question.  
11) FPU instructions are calculated to within 167 nS, 31 nS or 6 ns +- 2%
    dependent upon the instruction
11) FPU indexes include both register values and immediate values in the
    form #1.0
12) FPU speed in FLOPS is calculated as the total number of instructions
    divided by the time taken, this does not take account of common
    instructions
13) All FPU calculations with the exception of STF and LDF are done in
    extended precision.  STF and LDF are packed decimal precision
