本文讨论了流水线数列机的设计技术和多分之N的流水线设计方法,把各种复杂的运算统一在只用一个乘加器的流水线结构里。它能完成串型向量指令的串乘、串加。乘加型向量指令的褶积、平方和、FFT,利用泰勒级数展开式完成除法、平方根、三角函数、多项式等运算。当钟周期为140ns时,乘加速度为700万次/秒,实数1024点的FFT变换速度为2.87ms,除法速度为180万次/秒,平方根速度为190万次/秒。
This article discusses the design of pipelined serial machines and N-pipelined design methods that combine complex operations into a pipelined architecture that uses only one multiply accumulator. It can complete the string vector instruction string multiplication, string plus. Multiplication plus vector instructions convolution, sum of squares, FFT, the use of Taylor series expansions complete division, square root, trigonometric functions, polynomials and other operations. When the clock cycle is 140ns, the multiplication acceleration is 700 million times / second, the real 1024-point FFT transform speed is 2.87 ms, the division speed is 1.8 million times / second and the square root speed is 1.9 million times / second.
