Các thông số hiệu suất điện chính
Processor Core Architecture
Adopts Super Harvard dual SIMD parallel computing structure, equipped with two independent arithmetic processing units. Each unit contains ALU, hardware multiplier and barrel shifter to execute multiply-accumulate operations simultaneously in one instruction cycle.
Supports 32-bit single-precision floating-point, 40-bit extended precision floating-point, plus 8/16/32-bit fixed-point arithmetic calculation. Built-in dedicated hardware accelerators for FFT, FIR and IIR filtering algorithms to greatly shorten the runtime of common signal processing algorithms. It maintains full code compatibility with all previous SHARC series DSP chips.
On-Chip Memory Resources
Total integrated high-speed SRAM reaches 5 Mbits, which can be arbitrarily divided into program memory and data buffer memory according to application requirements. Multi-group independent internal buses eliminate internal data transmission bottlenecks and guarantee stable continuous streaming data processing performance. No on-chip flash memory is integrated; firmware must be loaded from external storage after power-on.
Integrated Peripheral Interfaces
- DAI configurable digital audio interface: supports I2S, TDM, SPDIF audio protocols, with built-in 8-channel asynchronous sample rate converters
- 8 SPORT synchronous serial ports for direct connection with audio codec chips
- Two high-speed Link Ports for multi-DSP cascading and high-speed point-to-point data transmission
- Dual SPI buses, 1 UART, I2C bus, 16-channel PWM output channels and three programmable hardware timers
- Embedded 16-bit DDR2 external memory controller for expanding large-capacity off-chip data storage
- Advanced multi-channel DMA controller with scatter-gather and delay-line DMA functions, completing background data transmission without occupying core computing resources
- IEEE 1149.1 standard JTAG debug interface for program downloading, online debugging and system fault diagnosis
Thông số kỹ thuật bộ nguồn
- Core digital supply voltage: 1.0V ~ 1.1V, typical value 1.05V
- Analog circuit and digital I/O power supply: fixed 3.3V
Thông số kỹ thuật về đóng gói và lắp ráp
Encapsulated in 324-pin CSPBGA surface-mount package with 19mm × 19mm body size. Compact outline saves PCB layout space for professional audio equipment, portable precision measuring instruments and embedded control boards.
Moisture Sensitivity Level: MSL3. All reflow soldering work must be finished within 168 hours once vacuum packaging is opened. Anti-static tray packaging is adopted to meet industrial mass production demands.
