STANDARD 80C32 TIMING
HIGH-SPEED OPERATION
The DS80C320/DS80C323 are built around a high-speed, 80C32-compatible core. Higher speed comes
not just from increasing the clock frequency but also from a newer, more efficient design.
In this updated core, dummy memory cycles have been eliminated. In a conventional 80C32, machine
cycles are generated by dividing the clock frequency by 12. In the DS80C320/DS80C323, the same
machine cycle is performed in 4 clocks. Thus the fastest instruction, one machine cycle, is executed three
times faster for the same crystal frequency. Note that these are identical instructions. Figure 2 shows a
comparison of the timing differences. The majority of instructions will see the full 3-to-1 speed
improvement. Some instructions will get between 1.5X and 2.4X improvement. Note that all instructions
are faster than the original 80C51. Table 1 shows a summary of the instruction set, including the speed.
The numerical average of all op codes is approximately a 2.5-to-1 speed improvement. Individual
programs are affected differently, depending on the actual instructions used. Speed-sensitive applications
would make the most use of instructions that are three times faster. However, the sheer number of 3-to-1
improved op codes makes dramatic speed improvements likely for any code. The Dual Data Pointer
feature also allows the user to eliminate wasted instructions when moving blocks of memory.
