1.0 Product Introduction
(Continued)
Below is a summary of the instructions that are directly ap-
plicable to graphics along with their intended use.
Instruction
Application
BBAND
BBOR
BBFOR
BBXOR
BBSTOD
BITWT
EXTBLT
The BITBLT group of instructions provide a
method of quickly imaging characters,
creating patterns, windowing and other
block oriented effects.
MOVMP
Move Multiple Pattern is a very fast
instruction for clearing memory and drawing
patterns and lines.
TBITS
Test Bit String will measure the length of 1’s
or 0’s in an image, supporting many data
compression methods (RLL), TBITS may
also be used to test for boundaries of
images.
SBITS
Set Bit String is a very fast instruction for
filling objects, outline characters and
drawing horizontal lines.
The TBITS and SBITS instructions support
Group 3 and Group 4 CCITT standards for
compression and decompression
algorithms.
SBITPS
Set Bit Perpendicular String is a very fast
instruction for drawing vertical, horizontal
and 45
§
lines.
In printing applications SBITS and SBITPS
may be used to express portrait and
landscape respectively from the same
compressed font data. The size of the
character may be scaled as it is drawn.
SBIT
CBIT
TBIT
IBIT
The Bit group of instructions enable single
pixels anywhere in memory to be set,
cleared, tested or inverted.
INDEX
The INDEX instruction combines a multiply-
add sequence into a single instruction. This
provides a fast translation of an X-Y
address to a pixel relative address.
2.0 Architectural Description
2.1 REGISTER SET
The NS32FX16 has 23 internal registers and a 384-byte
RAM array. 17 of these registers belong to the CPU portion
of the device and are addressed either implicitly by specific
instructions or through the register addressing mode. The
other 6 control the operation of the DSP Module, and are
memory mapped. Figure 2-1 shows the NS32FX16 internal
registers.
