With exceptions, instruction line, whether contains one, two, three, four 32-bit instructions, executes with throughput cycle ten-deep processor pipeline. optimal program execution, programmers must follow DSP's instruction parallelism rules when encoding instruction line. general, selection instructions that execute parallel each cycle depends instruction line resources each instruction requires source destination registers used instructions. programmer direct control three core components-the IALUs, compute blocks, program sequencer. ADSP-TS201S processor, most cases, two-cycle execution pipeline that fully interlocked, so-whenever computation result unavailable another operation dependent it-the automatically inserts more stall cycles needed. Efficient programming with dependency-free instructions eliminate most computational memory transfer data dependencies. addition, ADSP-TS201S processor supports SIMD operations ways-SIMD compute blocks SIMD computations. programmer load both compute blocks with same data (broadcast distribution) different data (merged distribution).

Multiplier-The multiplier performs both fixed- floating-point multiplication fixed-point multiply accumulate.
DUAL INTEGER (IALU)
ADSP-TS201S processor IALUs that provide powerful address generation capabilities perform many generalpurpose integer operations. IALUs referred assembly syntax have following features: Provides memory addresses data update pointers Supports circular buffering bit-reverse addressing Performs general-purpose integer operations, increasing programming flexibility Includes 31-word register file each IALU address generators, IALUs perform immediate indirect (pre- post-modify) addressing. They perform modulus bit-reverse operations with constraints placed memory addresses modulus data buffer placement. Each IALU specify either single-, dual-, quad-word access from memory. IALUs have hardware support circular buffers, reverse, zero-overhead looping. Circular buffers facilitate efficient programming delay lines other data structures required digital signal processing, they commonly used digital filters Fourier transforms. Each IALU provides registers four circular buffers, applications total eight circular buffers. IALUs handle address pointer wraparound automatically, reducing overhead, increasing performance, simplifying implementation. Circular buffers start memory location.
