Austin, TX--November 18, 1996--Motorola's Semiconductor Products Sector (Austin, TX) announced a price reduction and a performance increase for its 32-bit DSP96002 floating-point dual-port processor. By increasing the clock speed to 60 MHz and packaging the device in a more cost-effective CQFP, Motorola can now offer customers 90 million floating-point operations per second of performance for $49.95 in volume.
The foundation of the DSP96002 processing power is derived from a dual-memory Harvard-style architecture integrated with a large number of memories, ports, controllers, buses, and execution units working in parallel for maximum performance. The DSP96002 has three independent execution units that operate in parallel, dual 32-bit direct memory access (DMA) controllers which usher data on and off chip, six on-chip memories (2k words of RAM and 1k word of ROM that can occupy up to 2k word locations), two non-multiplexed 32-bit expansion bus ports which can be configured into one 64-bit port, two independent 32-bit expansion bus ports which can be configured into one 64-bit port, two independent 32-bit slave host ports which remove the need for glue logic when interfacing other processors, eight 32-bit buses (five data, three address) that combine for an internal bandwidth of 250 Mbytes per second, and an on-chip emulation controller which becomes the chip's own debugger.
The three independent execution units within the central processing unit are an IEEE single extended precision arithmetic logic unit (ALU) for central math and logical processing, a program control unit (PCU) for fetching, decoding, and dispatching instructions, and a dual address generation unit (AGU) that calculates addresses of data to be fetched from memory.
The DSP96002 is sampling now, and production volumes of the CQFP are priced at $49.95 for 10k units. A variety of software and application development tools for the DSP96002 are available from Motorola. Among these are a macro cross assembler, a linker/librarian, a simulator and C compiler, and a hardware evaluation board (application development system or ADS).
