Introduction
zSBX Expansion Module Socket
The zSBX expansion module socket is provided to customize the I/O
capabilities of the ZT 8832 to the needs of the application. The
expansion module interface is electrically, mechanically, and
functionally equivalent to the Intel iSBX MULTIMODULE
standard, including DMA support for high speed transfers to ZT 8832
memory. This makes hundreds of off-the-shelf modules available to
the STD bus designer. Functions available include servo and step
motor control, analog-to-digital and digital-to-analog conversion,
serial and parallel I/O, graphics, and modem control. There are also
prototyping boards for those who need to design custom I/O.
Numeric Data Processor
Socket
The math capabilities of the V40 include addition, subtraction,
multiplication, and division of 8-bit and 16-bit numbers. The STD bus
is often used in numerically intensive applications needing more
powerful arithmetic operations than those provided by the V40. These
requirements are realized with the addition of an 8087 Numeric Data
Processor (NDP) to the ZT 8832. Simply plugging the NDP into the
empty socket on the ZT 8832 provides 68 added instructions for
extended arithmetic, trigonometric, exponential, and logarithmic
functions. These added instructions are supported by seven additional
data types including integers (16-, 32-, and 64-bit), floating point (32-,
64-, and 80-bit), and BCD (18-digit). Using the NDP increases
performance up to 100 times that of equivalent routines implemented
in software.
