FUNCTIONAL DESCRIPTION
The TDA7502 contains one DSP Core and asso-
ciated peripherals.
24-BIT DSP CORE.
The DSP core is used to process the converted
analog audio data coming from the CODEC chip
via the SAI and return it for analog conversion.
Functions such as volume, tone, balance, and
fader control, as well as spatial enhancementand
general purpose signal processing may be per-
formedby the DSP.
Some capabilitiesof the DSPs are listed below:
Single cycle multiply and accumulate with con-
vergent rounding and condition code genera-
tion
2 x 56-bitAccumulators
Doubleprecision multiply
Scaling and saturation arithmetic
48-bit or 2 x 24-bit parallelmoves
64 interruptvector locations
Fastor long interrupts possible
Programmableinterrupt priorities and masking
8 each of Address Registers, Address Offset
Registersand Address Modulo Registers
Linear, Reverse Carry, Multiple Buffer Modulo,
Multiple Wrap-around Modulo address arith-
metic
Post-increment or decrement by 1 or by offset,
Indexby offset,predecrementaddress
Repeat instruction and zero overhead DO
loops
Hardware stack capable of nesting combina-
tions of 7 DO loops or 15 interrupts/subrou-
tines
Bit manipulation instructions possible on all
registers and memory locations. Also Jump on
bit test.
4 pin serial debug interface
Debug access to all internal registers, buses
and memory locations
5 worddeep program address historyFIFO
Hardware and software breakpoints for both
program and data memory accesses
Debug Single stepping, Instruction injection
and Disassembly of programmemory
DSP PERIPHERALS
There are a number of peripherals that are tightly
coupled to the DSP Core.Each of the peripherals
are listed below and described in the following
sections.
512 x 24-BitX-RAM.
512 x 24-BitY-RAM.
3072 x 24-Bit ProgramRAM
128 x 24-BitBoot ROM.

DATA AND PROGRAMMEMORY
Each of the memories are describedbelow.
512 x 24-Bit X-RAM (XRAM)
This is a 512 x 24-Bit Single Port SRAM used for
storing coefficients. The 16-Bit XRAM address,
XABx(15:0) is generated by the Address Genera-
tion Unit of the DSP core. The 24-Bit XRAM Data,
XDBx(23:0), may be written to and read from the
Data ALUof the DSP core. The XDBx Bus is also
connected to the Internal Bus Switch so that it
can be routedto and from all peripheral blocks.
512 x 24 Bit Y-RAM (YRAM)
This is a 512 x 24-Bit Single Port SRAM used for
storing
coefficients.
YABx(15:0) is generated by the Address Genera-
tion Unit of the DSP core. The 24-Bit Data,
YDBx(23:0), is written to and read from the Data
