Figure 2. Comparison of Cycles Per Instruction (CPI) between C51 and LP51 over all
In addition to the single-cycle CPU core, the AT89LP family of devices offers other
enhanced
improvements make the AT89LP family devices fit for low power, yet high performance
applications.
(36%) 24
Hardware Multiplier: Every AT89LP device includes a 2-cycle hardware multiplier
(8x8) with a 24 times speedup from the classic 48-clock MUL instruction. Some devices
also support signed/unsigned multiply support.
DSP: The AT89LP6440 introduced a multiply and accumulate (MAC) instruction with a
16x16 signed multiplier feeding a 40-bit accumulator. Along with FIFO addressing this
opens the 8051 world to low cost 16-bit digital signal processing applications with the
ability to perform FIR or IIR filtering routines at audio rates.
