Analog Devices has released two SHARC 32-bit floating point DSP families.
They are the performance-optimised 2148x, and the power-optimised 2147x - both with 3 or 5Mbit of zero wait-state on-chip memory.
"SHARC 2148x and SHARC 2147x series processors extend SHARC-calibre floating point processing to a new class of designs," said Jerry McGuire, v-p of DSP at Analog Devices.
The 400MHz (800Mmacs) 2148x has audio algorithms in ROM and is aimed at high definition (HD) single-chip audio and home theatre applications, as well as industrial applications requiring single-chip, floating point precision - motor control, for example.
2147x typically consumes 363mW, claims the firm, and is aimed at radar-based driver assistance systems like adaptive cruise control, blind spot detection and cross traffic alert, and portable medical devices.
These come in a 12x12mm package, operate at 105C, and run at up to 266MHz.
Both families include hardware accelerators for FFT, FIR, and IIR processing which have their own DMA mapping.
"The accelerators do not use the MACs, they are effectively separate hardware units. Once they are set-up and kicked-off, the processor doesn't have to intercede," ADI product marketing manager Andy Lanfear told EW.
Third-party support will be available from firms including AeVee Labs, Danville Signal Processing, DSP Concepts, Kaztek Systems, and the MathWorks.
