DSP Library

Elanix, Inc.iew Bit-True DSP Library supports fixed and floating-point arithmetic formats found in popular DSP chips. Both IEEE and C4x floating-point formats are supported by the library. While the IEEE format is nearly universal, the library includes support for several C4x formats, including standard and extended modes, as implemented on Texas Instruments floating-point DSPs. The DSP library tokens provide the ability to specify the bit length of both the exponent and the mantissa, and to inspect the resulting condition codes when simulating floating-point operations.

Features include:

• Bit-True System Design and Test
• Variable-Precision Support for C4x and IEEE Floating-Point Formats
• Variable-Precision Support for Unsigned or Signed Two's Complement Integer Formats
• Fixed Binary-point Integer Operations
• Primitive Integer Operations, such as Shift and Rotate
• Condition Outputs such as Underflow/Overflow Resulting from DSP Token Operation
• Various High-Level Functions Implemented with DSP Library Primitive Operations, such as FIR/IIR Filter Design, Detrend, Cross-Correlation, and FIFOs
• Various Discrete Transform Operators Including Mixed-Radix FFT and Discrete Sine/Cosine/Hadamard Transforms
