GENERAL DESCRIPTION
The Z89340 is a high-performance, programmable wave-
table engine designed for musical instruments, general
MIDI (Musical Instrument Digital Interface) sound modules,
digital mixing consoles with high-quality PC sound cards,
and computer-controlled multimedia applications.
This device features a 24-bit address bus for
addressing16-bit sample-storage ROM and DRAM (DRAM
refresh controller on-board), a 12x16 two’s-complement
scaler, eight 24-bit accumulators with clipping circuitry, a
2x8x16 interpolator to allow a high resolution of phase an-
gles between input samples, CD-quality sampling rates,
and 64 high-speed audio processing units (APUs) that can
be split into two low-speed APUs that operate at half the
sampling rate, allowing up to 128 notes to play simulta-
neously. All APUs are independent and can address any
part of data storage at any time.
The Z89340 can operate at output sampling rates up to 50
kHz, and offers eight channels of 16- to 20-bit serial output
data. The microprocessor interface allows full control of
frequency, amplitude, and sample data input to each oscil-
lator. The Z89340 features eight output registers, and their
contents can be sent to DAC or CODEC. Four of these can
be used for quadraphonic output, and have a panning
mechanism called Polar Pan that supports motion in all
four quadrants.
The other four output registers are used internally as ef-
fects channels, but can still send their data streams to a
DAC, a second Z89340, or other digital signal processor.
The Z89340 also has eight serial input data registers. In
addition, there are 24 stereo submix register pairs for use
in sending output data from one APU to be used as the in-
put to another.
In particular, the Z89340 is well-suited for 8- and 16-bit lin-
ear PCM recording/playback, wave synthesis, Sound
Blaster command set, and ADPCM (IMA/DVI) real-time de-
compression.
