[DSP编程] Ex3_3

TMS320C54x片内有1条程序总线,3条数据总线和4条地址总线。这3条数据总线(CB、DB和EB)将内部各单元连接在一起。其中,CB和DB总线传送从数据存储器读出的操作数,EB总线传送写到存储器中的数据。并行运算就是同时利用D总线和E总线。其中,D总线用来执行加载或算术运算,E总线用来存放先前的结果。 并行指令有并行加载和乘法指令,并行加载和存储指令,并行存储和乘法指令,以及并行存储和加/减法指令4种。所有并行指令都是单字单周期指令。并行运算时存储的是前面的运算结果,存储之后再进行加载或算术运算。这些指令都工作在累加器的高位,且大多数并行运算指令都受ASM(累加器移位方式位)影响。
TMS320C54x chip has a program bus, three data buses and four address buses. These three data buses (CB, DB and EB) connected to each unit within. Wherein, CB and DB bus transfer from the data memory read operand, EB bus transfer the data written to the memory. Parallel computing is the simultaneous use of D bus and E-bus. Wherein, D bus is used to perform arithmetic operation load or, E bus for storing the previous result. Parallel instruction with parallel load and multiply instructions, parallel load and store instructions, parallel storage and multiply instructions, as well as parallel storage and processing/subtract instruction four kinds. All instructions are single-word parallel single-cycle instructions. Parallel operation is stored when the result of the previous operation, and then be loaded or stored arithmetic. These commands are working in the accumulator high, and most parallel arithmetic instructions are protected by ASM (accumulator shift mode bits) affected. (2013-08-22, Visual C++, 4KB, 下载1次)

FIRPM公园,麦克莱伦最佳equiripple FIR滤波器的设计。乙= FIRPM(不适用,女,甲)返回一个长度为N +1线性相位(真实,对称系数)FIR滤波器具有最佳逼近到所需的频率响应的F和描述在极小极大意义的。F是成对频带边缘载体,以递增0和1之间秩序。 1对应于奈奎斯特频率或采样频率的一半。至少有一个频段必须有一个非零宽度。 A是一个真正的载体,作为F的指定由此得到的滤波器的频率响应所需的幅度B相同大小
FIRPM Parks-McClellan optimal equiripple FIR filter design. B=FIRPM(N,F,A) returns a length N+1 linear phase (real, symmetric coefficients) FIR filter which has the best approximation to the desired frequency response described by F and A in the minimax sense. F is a vector of frequency band edges in pairs, in ascending order between 0 and 1. 1 corresponds to the Nyquist frequency or half the sampling frequency. At least one frequency band must have a non-zero width. A is a real vector the same size as F which specifies the desired amplitude of the frequency response of the resultant filter B.
