Preface
The ARM610 is a general purpose 32-bit microprocessor with
4
kByte cache, write buffer and Memory
Management Unit (MMU) combined in a single chip. The ARM610 offers high level RISC performance yet
its fully static design ensures minimal power consumption, making it ideal for portable, low-cost systems.
The innovative MMU supports a conventional two-level page-table structure and a number of extensions
which make it ideal for embedded control, UNIX and Object Oriented systems. This results in a high
instruction throughput and impressive real-time interrupt response from a small and cost-effective chip.
Applications
The ARM610 is ideally suited to those applications requiring RISC performance from a compact, power
efficient processor. These include:
•
•
•
•
•
•
Personal computer devices eg.PDAs
High-performance real-time control systems
Portable telecommunications
Data communications equipment
Consumer products
Automotive
