MOS INTEGRATED CIRCUIT

µPD77016

16 bits, Fixed-point Digital Signal Processor

µPD77016 is a 16 bits fixed-point DSP (Digital Signal Processor) developed for digital signal processing with its

demand for high speed and precision.

FEATURES

• FUNCTIONS

• Instruction cycle: 30 ns (MIN.) with 33 MHz clock

• Dual load/store

• Hardware loop function

• Conditional execution

• Executes product-sum operation in one instruction cycle

• PROGRAMMING

• 16 bits × 16 bits + 40 bits → 40 bits multiply accumulator

• 8 general registers (40 bits each)

• 8 ROM/RAM data pointer: each data memory area has 4 registers

• 10 source interrupts (external: 4, internal: 6)

• 3 operand instructions (example: R0 = R0 +R1L R2L)

• Nonpipeline on execution stage

• MEMORY AREAS

• Program memory area: 64K words × 32 bits

• Two independent data memory areas: 64K words × 16 bits (X/Y memory)

• ON-CHIP PERIPHERAL

• I/O port: 4 bits

• Serial I/O (16 bits): 2 channels

• CMOS

• +5 V single power supply
