1.1 MN102H Series Overview
The 16-bit MN102H series is the high-speed linear addressing version of the
MN10200 series. The new architecture in this series is designed for C-language
programming and is based on a detailed analysis of the requirements for
embedded applications. From miniaturization to power savings, it provides for a
wide range of needs in user systems, surpassing all previous architectures in
speed and functionality.
This series uses a load/store architecture for computing within the registers rather
than the accumulator system for computing within the memory space, which
Panasonic has used in most of its previous major series. The basic instructions
are one byte/one machine cycle, drastically shrinking code size and improving
compiler efficiency. The circuit is designed for submicron technology, providing
optimized hardware and low system power consumption.
The devices in this series contain up to 16 megabytes of linear address space and
enable highly efficient program development. In addition, the optimized
hardware structure allows for low system-wide power consumption even in large
systems.
1.2 MN102H Series Features
Designed for embedded applications, the MN102H series contains a flexible and
optimized hardware architecture as well as a simple and efficient instruction set.
It provides both economy and speed. This section provides the features of the
MN102H series CPU.
■ High-speed signal processing
An internal multiplier multiplies two 16-bit registers for a 32-bit product in a
single cycle. In addition, the hardware contains a saturation calculator to
ensure that no signal processing is missed and to increase signal processing
speed.
■ Linear addressing for large systems
The MN102H series provides up to 16 megabytes of linear address space.
With linear addressing, the CPU does not detect any borders between
memory banks, which provides an effective development environment. The
hardware architecture is also optimized for large-scale designs. The memory
is not divided into instruction and data areas, so operations can share
instructions.
