24 bit DSP core
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
