TriMedia TM-1300
Continuing a tradition of high-performance, low-cost
media processors, the TriMedia™ TM-1300 delivers up
to 66% more processing power1 to multimedia applica-
tions at a lower unit cost. By combining a 166-MHz
CPU and a full complement of enhanced on-chip I/O
and coprocessing units, TM-1300 achieves up to 6.5 bil-
lion operations per second—ideal for applications
requiring real-time processing of video, audio, graphics,
and communications datastreams.
TM-1300 boosts performance through a faster clock
speed and a faster main memory interface than previ-
ous TriMedia processors. Datastream I/O is enhanced
with a new on-chip unit for handling audio output in
Sony/Philips digital format (SPDIF). Lower power con-
sumption and a smaller footprint contribute to making
the TM-1300 a more efficient and compact processing
solution for new multimedia designs.
TM-1300 is an ideal building block for applications requiring
simultaneous processing of several types of multimedia data-
streams. With ample computational power available to capture,
compress and decompress many video and audio data formats in
real time, TM-1300 is well suited for a broad range of video-
centric applications such as videoconferencing, video editing,
video-based security, surveillance, or industrial inspection systems,
and multifunctional devices such as digital TV sets and set-top
boxes. It also supports applications in a Java™ virtual machine
environment.
With its comprehensive software development environment, the
TriMedia SDE, TM-1300 is comparable in ease of programmabil-
ity to general-purpose processors. The SDE enables multimedia
application development entirely in the C and C++ languages
improving time-to-market and lowering product development and
maintenance costs.

MEMORY SYSTEM OVERVIEW
To meet the performance requirements of its target appli-
cations while maintaining low cost, the TM-1300 memory
subsystem couples substantial on-chip caches with a glue-
less memory interface through a unique internal bus or
data highway.
Dedicated instruction and data cache—The TM-1300 CPU is sup-
ported by separate, dedicated on-chip data and instruction caches that
employ a variety of techniques to improve cache hit ratios and thus
CPU performance.
The dual-ported data cache allows two simultaneous accesses. It is
non-blocking thus cache misses and CPU cache accesses can be han-
dled simultaneously. Early restart techniques reduce read-miss latency.
Background copyback reduces CPU stalls.
To reduce internal bus bandwidth requirements, instructions in main
memory and cache use a compressed format. Instructions are decom-
pressed in the instruction cache decompression unit before being
processed by the CPU.
To improve cache behavior and thus performance, both caches have a
locking mechanism. Cache coherency is maintained by software.
Glueless memory system interface—The TM-1300 couples main
memory to substantial on-chip caches through a glueless main memo-
ry interface (MMI). The MMI acts as the main memory controller
and programmable central arbiter that allocates memory bandwidth
for on-chip peripheral unit activities.
Support for a variety of memory configurations enables a wide variety
of TM-1300-based systems to be built. The MMI supports 16-Mbit
and 64-Mbit SDRAMs and provides sufficient drive capacity for an
up to 143-MHz memory system comprising 8-MB (one 2Mx32), 16-
MB (two 4Mx16 or two 2Mx32), or 32-MB (four 4Mx16 or four
2Mx32) memories. Larger memories (up to 64 MB) can be imple-
mented using lower memory system clock frequencies or external
buffers. Higher bandwidth SDRAM permits TM-1300 to use a nar-
rower and simpler interface than is required to achieve similar perfor-
mance with standard DRAM. Programmable speed ratios allow
SDRAM to have a different clock speed than the TM-1300 CPU.
HIGH-SPEED INTERNAL BUS (DATA HIGHWAY)
The TM-1300 CPU and processing units access external SDRAM
through the on-chip internal bus or data highway comprising separate
32-bit address and data buses. Handled by the MMI, programmable
bus arbitration enables the data highway to maintain real-time respon-
siveness in a variety of applications.
ROBUST SOFTWARE DEVELOPMENT ENVIRONMENT
The TriMedia SDE includes a full suite of system software tools to com-
pile and debug code, analyze and optimize performance, and simulate
execution for the TM-1300 processor. The SDE dramatically lowers
development costs, reduces time-to-market, and ensures code portability
to next generation architecture by enabling development of multimedia
applications entirely in the C and C++ programming languages.
The TriMedia SDE Version 2.0 also supports Metrowerks®
CodeWarrior® plug-ins. These plug-ins enable programmers to
develop C code for TriMedia processors using the popular Code-
Warrior Integrated Professional Development Environment (IDE).
TRIMEDIA APPLICATION LIBRARIES
Many TriMedia application libraries are available to accelerate product
development of common standard-compliant software algorithms used
in processing multimedia datastreams. These C-callable routines are
optimized for top performance on the TriMedia architecture.
Application libraries are available from Philips and third-party suppli-
ers and include functions such as MPEG-1 encode or decode, MPEG-
2 MP@ML decode, MPEG-2 1/2D1 MP@ML encode, H.320,
H.324, Dolby ProLogic or Dolby Digital (AC-3) decode, communica-
tions protocols, and many more. The TM-1300 can also support Java
applications with third-party Java virtual machine environments.
