1.1 TMS320 Family
The TMS320 family consists of fixed-point, floating-point, and multiprocessor
digital signal processors (DSPs). TMS320 DSPs have an architecture de-
signed specifically for real-time signal processing. The following characteris-
tics make this family the ideal choice for a wide range of processing applica-
tions:
Flexible instruction sets
High-speed performance
Innovative parallel architectures
Cost effectiveness
1.1.1 History, Development, and Advantages of TMS320 DSPs
In 1982, Texas Instruments introduced the TMS32010, the first fixed-point
DSP in the TMS320 family. Before the end of the year,
Electronic Products
magazine awarded the TMS32010 the title “Product of the Year”. Today, the
TMS320 family consists of these generations: ’C1x, ’C2x, ’C2xx, ’C5x, and
’C54x fixed-point DSPs; ’C3x and ’C4x floating-point DSPs; and ’C8x multipro-
cessor DSPs. See Figure 1–1.
Devices within a generation of the TMS320 family have the same CPU struc-
ture but different on-chip memory and peripheral configurations. Spin-off de-
vices use new combinations of on-chip memory and peripherals to satisfy a
wide range of needs in the worldwide electronics market. By integrating
memory and peripherals onto a single chip, TMS320 devices reduce system
cost and save circuit board space.
