TDA7590

24 bit DSP core

17/42

24 bit DSP core

The DSP core is a general purpose 24-bit DSP. The main feature of the DSP core are listed

below:

●

120 MHz operating frequency (120 MIPS)

●

Fully pipelined 24 x 24 bit parallel multiplier-accumulator

●

Saturation/limiting logic

●

56-bit parallel barrel shifter

●

Linear, reverse carry and modulo addressing modes

●

24-bit address buses for program, X and Y data spaces and DMA

●

Memory-expandible hardware stack

●

Nested zero-overhead DO loops

●

Fast interrupts

●

Powerful JTAG emulation port

●

Software wait and stop low power standby modes

●

Program address tracing support

●

Two 24-bit data moves in parallel with arithmetic operations

●

External interrupts including non-maskable interrupt

●

Interrupts may be independently masked and prioritized

●

Bit-manipulation instructions can access any register or memory location

●

On board support for DMA controller
