IBM Corp’s San Jose, California-based IBM Microelectronics Division has a new signal processor for its Mwave technology environment. The MDSP2020 and MDSP2021 are designed for notebook computers, including ones with PCMCIA format and mobile communications. They operate at multiple clock rates up to 33 MIPS. The new Mwave DSP 2000 series has on-chip peripheral interface integration, 20Kb of program and data memory on-chip, expandable to 160Kb off-chip. It offers Musical Instrument Digital Interface port and Universal Asynchronous Receiver-Transmitter emulation. An integrated AT bus interface, including bus mastering, provides the connection between the host system and the Mwave, enabling high-speed data transfers for implementation of input-output-intensive applications. Telephony and audio coder-decoder interfaces for widely used signal interfacing chips are also part of the standard integrated peripherals in the Mwave chips. It is available now in sample quantities and in two versions – MDSP2020 with integrated memory for customers who need a complete subsystem on a chip and MDSP2021, supporting broader functionality. No prices were given.
