DSP systems– interfacing
with the outside world 4
CHAPTER
In this chapter many issues related to DSP peripheral components will be consid-
ered. This will include a consideration of both on- and off-chip components and
their operation. Many ideas presented in Chapter 3 such as the use of efficient
pipelines, fast data manipulation and arithmetic operations all rely on the ability of a
DSP device to move large amounts of data quickly and seamlessly into and out of
the DSPs processing core. To facilitate this effective movement and storage of data,
most DSPs incorporate a wide range of peripheral management facilities and these
will be considered here. As with Chapter 3, a hypothetical DSP device will be intro-
duced which incorporates a generic set of typical features. The hypothetical device
will be used as the basis for discussions and then related to real life examples, again
taken mainly from the Texas Instruments range of DSP devices.
