CMOS IC

LC83010N, 83010NE

Audio Digital Signal Processor

Overview

The LC83010N, 83010NE is a single-chip digital signal

processor (DSP). It is designed for use in the application

fields such as a digital processing of audio signals.

The LC83010N, 83010NE CMOS processor has various

on-chip filtering circuits such as a graphic equalizer for

reproduction of sound quality. It also has simulation cir-

cuit for reverberation (sound reflection and echo), so that

sound field with surround and delay can be created.

The LC83010N and LC83010NE are upgraded versions of

the LC83010 and the LC83010E. The LC83010N and

LC83010NE have a 64fs clock output that enables improved

interfacing with external A/D converters. TEST5 has been

renamed FS640/T5 and incorporates both the new clock

output and the original test output.

Features

LSI functions

• Dual Harvard Architecture: Enables simultaneous pro-

cessing (multiply and addition) of stereo signals in a single

instruction cycle.

The LC83010N, LC83010NE processor has the follow-

ing two independent units:

· Multiplier : 24 bits × 16 bits (fixed-point decimal)

· ALU : 32-bit arithmetic calculation, 24-bit arithmetic

and logical operations.

· Temporal Registers (TMP0 to TMP7) : 32-bit for each

· Internal Memory Data RAM

128 × 24 bits

Coefficient RAM 256 × 16 bits

Constant ROM 256 × 24 bits

• Program memory Capacity (RAM) : 320 × 32 bits

• A variety of I/O interfaces.

· Audio signal I/O :

1 channel for input (applicable to various formats)

3 channel for output (applicable to up to 4 types of data

format)

· Surround DRAM access signal :

16 accesses/CH Max. (within 1 fs)

Up to 2 256K (64K × 4 bits) DRAMs or 1M (256K × 4

bits) DRAMs can be directly connected to this chip.
