المعلمات الأساسية لأداء النظام الكهربائي
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.
