Figure 2. ADSP-21364 System Sample Configuration

Independent, Parallel Computation Units

Single-Cycle Fetch of Instruction and Four Operands

Within each processing element is a set of computational units.

The computational units consist of an arithmetic/logic unit

(ALU), multiplier, and shifter. These units perform all opera-

tions in a single cycle. The three units within each processing

element are arranged in parallel, maximizing computational

throughput. Single multifunction instructions execute parallel

ALU and multiplier operations. In SIMD mode, the parallel

ALU and multiplier operations occur in both processing ele-

ments. These computation units support IEEE 32-bit, single-

precision floating-point, 40-bit, extended-precision floating-

point, and 32-bit, fixed-point data formats.

The ADSP-21364 features an enhanced Harvard architecture in

which the data memory (DM) bus transfers data and the pro-

gram memory (PM) bus transfers both instructions and data

(see Figure 1 on Page 1). With the ADSP-21364’s separate pro-

gram and data memory buses and on-chip instruction cache,

the processor can simultaneously fetch four operands (two over

each data bus) and one instruction (from the cache), all in a sin-

gle cycle.

Instruction Cache

The ADSP-21364 includes an on-chip instruction cache that

enables three-bus operation for fetching an instruction and four

data values. The cache is selective—only the instructions whose

fetches conflict with PM bus data accesses are cached. This

cache allows full-speed execution of core, looped operations

such as digital filter multiply-accumulates, and FFT butterfly

processing.

Data Register File

A general-purpose data register file is contained in each

processing element. The register files transfer data between the

computation units and the data buses, and store intermediate

results. These 10-port, 32-register (16 primary, 16 secondary)

vard architecture, allow unconstrained data flow between

computation units and internal memory. The registers in PEX

are referred to as R0–R15 and in PEY as S0–S15.

Data Address Generators with Zero-Overhead Hardware

Circular Buffer Support

The ADSP-21364’s two data address generators (DAGs) are

used for indirect addressing and implementing circular data

buffers in hardware. Circular buffers allow efficient program-

ming of delay lines and other data structures required in digital
