Austin, Texas - Motorola Inc. has moved its 56L307 digital signal processor into production. The DSP, a HiP4 follow-on to the 24-bit DSP56307, claims performance of 290 effective DSP Mips, or 60 percent higher performance than its predecessor.
The older part is used in multichannel networking applications. The new, pin-compatible model allows customers to reduce their cost per channel or add features-for example, integrated access devices, which add voice to DSL digital data products.
The new chip operates at 160 MHz at 1.8 volts and integrates 64 kwords of memory. Its 160-MHz enhanced filter coprocessor is said to process filter algorithms in parallel with core operations.
David Baczewski, strategic-marketing manager for Motorola's Wireless Infrastructure Systems Division, said the filter can provide as much as 130 Mips of additional processing performance beyond the 160-Mips core, for a total of 290 effective Mips. The coprocessor alone can boost processing performance by 80 percent over DSPs without one, he said, and designs based on the new DSP can offer higher channel density at a lower cost without consuming more board space or power.
The DSP56L307 is available now at $26.50 in quantities of 10,000.
