TriMedia TM-1000

Program m able Media Processor

The TriMedia™ TM-1000 is a general-purpose microprocessor for

real-time processing of audio, video, graphics, and communications

datastreams. In a single chip, TM-1000 combines an ultra-high

performance, low cost CPU with a full complement of I/O and

coprocessing peripheral units.

In consumer electronics appliances and personal computing prod-

ucts, the TM-1000 media processor performs multimedia functions

with the advantages of special-purpose, embedded DSP solutions —

low cost and single-chip packaging — and the programmability of

general-purpose CPUs. It improves time-to-market through high-

level C/C++ language programmability and delivers throughput of

up to four billion operations per second.

MULTIMEDIA APPLICATIO NS

TM-1000 is an ideal building block for any multimedia application

that requires processing of video, audio, graphics, and communica-

tions datastreams. It is well suited for applications ranging from

single-purpose systems such as videophones, to reprogrammable,

multipurpose devices such as set-top boxes or web browsers.

TM-1000 easily implements popular multimedia standards such as

MPEG-1 and MPEG-2, but its orientation around a powerful, pro-

grammable general-purpose CPU makes it capable of a variety of

multimedia algorithms, whether open or proprietary.

FEATURES

+ Processes audio, video, graphics, and communications

datastreams on a single chip

+ Powerful, ﬁne-grain parallel, 100 MHzVLIW CPU with

HARNESSING THE POW ER O F VLIW

separate instruction and data caches

TM-1000 delivers top performance through its elegant implementa-

tion of a ﬁne-grain parallel architecture known as very-long instruc-

tion word, or VLIW. Unique to the TriMedia processor’s VLIW

implementation, parallelism is optimized at compile time by the

TriMedia compilation system. No specialized scheduling hardware is

required to parallelize code during execution. Hardware saved by

eliminating complex scheduling logic reduces cost and allows the

integration of multimedia-speciﬁc features.

+ Independent, DMA-driven multimedia I/O units to

format data and multimedia coprocessors to ofﬂoad

the TriMedia CPU of speciﬁc multimedia algorithms

+ High-performance bus and memory system to manage

communication between TriMedia processing units

+ Instruction set includes RISC, multimedia, SIMD-type

With the capacity to pack multiple operations into one VLIW

instruction and 27 functional units in which to process them,

TM-1000 can execute up to ﬁve operations in parallel with each

clock cycle. Such parallel processing is an ideal complement to the

inherently parallel nature of multimedia applications.

DSP, and IEEE-compliant ﬂoating point operations

+ Robust software development tools and libraries that

enable multimedia application development entirely in

C/C++ programming languages

Another key contributor to TM-1000’s top performance is its use of

conditional execution. During program creation, an instruction

scheduler adds conditional code to each operation to enable guarded

execution — a technique that increases ﬁne-grain parallelism and

signiﬁcantly decreases code branching and execution time.

+ Conﬁgurable for standalone and plug-in card applica-

tions in consumer electronics and PC products
