SUMMARY

High performance 32-bit audio processor

Super Harvard Architecture Computer (SHARC)

4 independent buses for dual data, instruction, and

nonintrusive, zero-overhead I/O fetch on a single cycle

Code compatible with all other SHARC family DSPs

Single-instruction-multiple-data (SIMD) computational

architecture—two 32-bit IEEE floating-point computa-

tion units, each with a multiplier, ALU, shifter, and

Rev. 0

DUAL-PORTED BLOCKS

Serial ports offer I

simultaneous receive or transmit pins, which support up

to 16 transmit or 16 receive channels of audio

Integrated peripherals—integrated I/O processor,

0.5 Mbit on-chip SRAM, SDRAM controller, glueless

multiprocessing features, and I/O ports (serial, link,

external bus, SPI®, and JTAG)

SHARC Mel-100 supports 32-bit fixed-point, 32-bit

floating-point, and 40-bit floating-point formats
