Overview
1.1 Overview
1.1.2 Built-in Multiply-Accumulate Operation Function
(1) Built in high-speed multiplier
The M32R incorporates a 32-bit x 16-bit high-speed multiplier/accumulator which allows the
processor to execute a 32-bit x 32-bit integer multiplication instruction in three cycles (one
cycle is 25 ns when CPU memory clock = 40 MHz).
(2) Supports Multiply-Accumulate operation instructions comparable to DSP
The M32R supports the following four modes of Multiply-Accumulate operation instructions (or
multiplication instructions) based on a 56-bit accumulator:
16 high-order register bits x 16 high-order register bits
16 low-order register bits x 16 low-order register bits
All 32 register bits x 16 high-order register bits
All 32 register bits x 16 low-order register bits
The M32R has instructions to round off the value stored in the accumulator to 16 or 32 bits, as
well as instructions to shift the accumulator value to adjust digits and store the digit-adjusted
value in a register. These instructions also can be executed in one cycle, so that when
combined with high-speed data transfer instructions such as Load & Address Update and
Store & Address Update, they enable the M32R to exhibit high data processing capability
comparable to that of DSP.
1.1.3 Built-in Flash Memory and RAM
The 32172/32173 contains flash memory and RAM that can be accessed with no wait states,
making it possible to build a high-speed embedded system.
The internal flash memory allows for on-board programming (you can write to it while being
mounted on the printed circuit board). Use of flash memory means the chip engineered at the
development phase can be used directly in mass-production, so that you can smoothly migrate
from prototype to mass-production without changing the printed circuit board.
The internal flash memory can be rewritten 100 times.
The internal flash memory has a virtual-flash emulation function, allowing the internal RAM
tobe artificially mapped into part of the internal flash memory. This function, when combined
with the internal Real-Time Debugger (RTD), facilitates data tuning on ROM tables.
The internal RAM can be accessed for read or rewrite from an external device independently of
the M32R by using RTD (real-time debugger). It is communicated with external devices by
RTD's exclusive clock-synchronized serial I/O.
