INTRODUCTION
The UT699 is a pipelined monolithic, high-performance, fault-
tolerant SPARC
TM
V8/LEON 3FT Processor. The UT699
provides a 32-bit master/target PCI interface, including a 16 bit
user I/O interface for off-chip peripherals. A compliant 2.0
AMBA bus interface integrates the on-chip LEON 3FT,
SpaceWire, Ethernet, memory controller, cPCI, CAN bus, and
programmable interrupt peripherals.
The UT699 is SPARC V8 compliant; compilers and kernels for
SPARC V8 can therefore be used industry standard
development tools. A full software development suite is
available including a C/C++ cross-compiler system based on
GCC and the Newlib embedded C-library.
BCC includes a small run-time kernel with interrupt support
and Pthreads library. For multi-threaded applications, a
SPARC
TM
compliant port of the eCos real-time kernel, RTEMS
4.6.5, and VxWorks 6.x is supported.

1.0 Introduction
The UT699 LEON 3FT processor is based upon the industry-standard SPARC V8 architecture. The system-on-chip incorporates the
SPARC V8 core and the peripheral blocks indicated below. The core and peripherals communicate internally via the AMBA
(Advanced Microcontroller Bus Architecture) backplane. This bus is comprised of the AHB (Advanced High-speed Bus) which is
used for high-speed data transfer, and the APB (Advanced Peripheral Bus) which is used for low-speed data transfer.
