Motorola Accelerates DSP56002 to 80 MHz.AUSTIN, Texas--(BUSINESS WIRE)--May 22, 1995--Motorola (NYSE NYSE See: New York Stock Exchange : MOT) Microcontroller Technologies Group's Digital Signal Processor A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing. Characteristics of typical Digital Signal Processors
The new 80 MHz processor is now the most powerful in Motorola's industry-standard, 24-bit DSP56000 family; Motorola also offers the DSP56002 at 40 and 66 MHz. At 80 MHz, the DSP56002 offers one of the highest performance levels in the industry, delivering 40 million DSP instructions per second Instructions per second (IPS) is a measure of a computer's processor speed. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and even applications, (MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. ) and 240 million operations per second (MOPS). This speed increase enables the DSP56002 to perform multiple tasks simultaneously and run more sophisticated functions, such as high-compression-rate vocoders, high-quality voice compression, and transmission modulation and demodulation. "The demands for raw performance from a DSP continue to increase as the market develops more sophisticated applications," said Keith Essency, Motorola DSP Division 24/32-bit operations manager. "Motorola's significant investment in state-of-the-art fabrication facilities and technology allowed us to attain the 80 MHz clock speed and allowed for higher production volumes. We expect to deliver even higher speeds in the near future." Motorola's 24-bit DSP Architecture In addition to its flagship DSP56002 product, Motorola's 24-bit product line includes the DSP56L002 (a low-power version), DSP56004, DSP56004ROM, DSP56005 (also announced today), DSP56007 and DSP56L007 (a low-power version). Motorola's DSP56000 architectural features include a fully-static 24-bit DSP core with three independent execution units -- the data arithmetic logic unit See ALU. , a program control unit and an address arithmetic unit. The DSP56002 also features 512-word program RAM, two 256-word data RAMs and two pre-programmed data ROMs. Peripherals include a host interface, a synchronous serial interface (SSI (1) See server-side include and single-system image.

Motorola's on-chip emulation (OnCE(tm)) completes a full set of peripherals by offering a non-intrusive debugging function. Motorola also provides a wide variety of software and hardware development tools designed for the DSP56000 products, including assemblers, simulators, linkers, C compilers, application development systems and a new DSP56002 Evaluation Module (EVM), also announced today. Pricing and Availability The 80 MHz DSP56002 is sampling now and will be available in production volumes in June 1995 in 144-pin, thin quad flatpack (TQFP See QFP. ) packages for a suggested resale price of U.S. $38.20 per unit in 1,000 piece quantities. -0- Note: Photos available upon request. -0- Having 1994 worldwide sales of $6.9 billion, Motorola's Semiconductor Products Sector is the largest U.S.-based broad line supplier of semiconductors, with a balanced portfolio of more than 50,000 devices. Motorola is one of the world's leading providers of wireless communication, semiconductors, and advanced electronic systems and services. Major equipment businesses include cellular telephone, two-way radio, paging and data communications, personal communications, automotive, defense and space electronics and computers. Communication devices, computers and millions of consumer products are powered by Motorola semiconductors. Motorola's 1994 sales were $22.2 billion.
