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.
