TDA7500
FUNCTIONAL DESCRIPTION
The TDA7500 IC broken up into two distinct blocks. One block contains the two DSP Cores and their associated
peripherals. The other contains the ADC, DAC and the RDS filter, demodulator and decoder.
24-BIT DSP CORE
The two DSP cores are used to process the audio and FM/AM data, coming from the ADC, either any kind of
digital data coming via SPDIF or SAI. After the digital signal processing these data are sent to the DAC for an-
alog conversion. Functions such as volume, tone, balance, and fader control, as well as spatial enhancement
and general purpose signal processing may be performed by the DSP0. When FM/AM mode is selected, DSP1
is fully devoted to AM/FM processing. Nevertheless it can be used for any kind of different application, when a
different input source is selected.
Some capabilities of the DSPs are listed below:
s
Single cycle multiply and accumulate with convergent rounding and condition code generation
s
2 x 56-bit Accumulators
s
Double precision multiply
s
Scaling and saturation arithmetic
s
48-bit or 2 x 24-bit parallel moves
s
64 interrupt vector locations
s
Fast or long interrupts possible
s
Programmable interrupt priorities and masking
s
8 each of Address Registers, Address Offset Registers and Address Modulo Registers
s
Linear, Reverse Carry, Multiple Buffer Modulo, Multiple Wrap-around Modulo address arithmetic
s
Post-increment or decrement by 1 or by offset, Index by offset, predecrement address
s
Repeat instruction and zero overhead DO loops
s
Hardware stack capable of nesting combinations of 7 DO loops or 15 interrupts/subroutines
s
Bit manipulation instructions possible on all registers and memory locations, also Jump on bit test
s
4 pin serial debug interface
s
Debug ccess to all internal registers, buses and memory locations
s
5 word deep program address history FIFO
s
Hardware and software breakpoints for both program and data memory accesses
s
Debug Single stepping, Instruction injection and Disassembly of program memory
DSP PERIPHERALS
There are a number of peripherals that are tightly coupled to the two DSP Cores. Same of the peripherals are
connected to DSP 0 others are connected to DSP1.
