INTRODUCTION
TM1300 is a successor to the TM1100 and TM1000 me-
dia processors. For those familiar with the TM1100, the
new features specific to the TM1300 are summarized in
Section 2.6. For those familiar with the TM1000, new
features for the TM1300 are summarized in Section 2.7.

TM1300 FUNDAMENTALS
TM1300 is a media processor for high-performance mul-
timedia applications that deal with high-quality video and
audio. These applications can range from low-cost, ded-
icated systems such as video phones, video editing, dig-
ital television, security systems or set-top boxes to repro-
grammable, multipurpose plug-in cards for personal
computers. TM1300 easily implements popular multime-
dia standards such as MPEG-1 and MPEG-2, but its ori-
entation around a powerful general-purpose CPU (called
the DSPCPU) makes it capable of implementing a vari-
ety of multimedia algorithms, both open and proprietary.
TM1300 is also easily configured in multiple processor
configurations for very high-end applications.
More than just an integrated microprocessor with unusu-
al peripherals, the TM1300 is a fluid computer system
controlled by a small real-time OS kernel running on a
very-long instruction word (VLIW) processor core.
TM1300 contains a DSPCPU, a high-bandwidth internal
bus, and internal bus-mastering DMA peripherals.
