摘要 介绍了一种称为GDSP的针对多协议处理的16位定点专用DSP,它具有一条指令完成取双操作数、运算及结果写回memory的特点,针对算法特点设计的三角函数运算单元CDC、二进制对数/指数运算的算法改进及VLSI实现的对数运算单元LOG和指数运算单元ANTILOG,能快速精确的完成三角函数和对数/指数的求解。该DSP系统在保证精度的同时,具有强大的运算能力。 A 16 bit fixed point special DSP called GDSP for multi-protocol is described. This DSP can complete the operation that fetch two operand, compute the result and then write back result by using only one instruction, has the special unit CDC for compute the result of trigonometric function such as cos(x) and arcos(x), improves the binary-to-binary logarithm and anti-logarithm linear approximation including the VLSI implementation of computation unit LOG for logarithm and ANTILOG for anti-logarithm.
