LSI403Z Digital Signal Processor
T I M E R S
The LSI403Z has two identical 16-bit on board timers for real-time interrupt
generation. Each timer is fully programmable, and has a 6-bit prescaler and
interrupt capability. The timers can automatically reload with the initial count so
that periodic interrupts can be generated.
T D M S E R I A L P O R T S
The LSI403Z provides two identical synchronous serial ports that support
8- or 16-bit active or passive transfers, which can be either burst or continuous.
It a maximum transfer rate in either active or passive mode of one-half the
processor clock rate. Both serial ports provide the programmable feature of a
TDM (time division multiplex) mode that is compatible with T1/E1 framers or
the local serial bus of H.100/H.110 interface devices. The TDM mode can
also be used to establish a serial multiprocessor communication link with only
three signals.
H O S T P R O C E S S O R I N T E R F A C E ( H P I )
The Host Processor Interface, or HPI, is an asynchronous 8-bit parallel port
that is used to interface with off-chip devices. It is compatible with both
Motorola and Intel style memory interfaces, and supports word transfers. The
maximum transfer rate for the HPI is one-forth of the processor clock frequency.
D E V E L O P M E N T T O O L S
The LSI403Z is fully supported by both LSI Logic and third party
commercial tools. LSI Logic provides a GNU-based compiler, linker and
assembler available for Windows and Solaris platforms. The compiler supports
C fixed-point data types and employs a variety of C intrinsic functions. Also
supported is a full commercial tool chain from GreenHills Software and Corelis
JTAG debug tools. The ZSP architecture enables the C compiler to produce
code unrivaled in code density and execution speed by any DSP in its class,
offering a fast time to market with optimal performance and cost.
An LSI403Z evaluation board, the EB403, is available offering the
following features:
32-bit PCI interface provides JTAG debug capabilities
16-bit A/D converter on board
Reference board with the ability to handle multiple voice channels
Programmable Gain Amplifier
