Glossary
DSP_minval:
Minimum value of a vector.
DSP_mul32:
32-bit vector multiply.
DSP_neg32:
32-bit vector negate.
DSP_q15tofl:
Q15 to float conversion.
DSP_radix2:
Complex forward FFT (radix 2).
DSP_recip16:
16-bit reciprocal.
DSP_r4fft:
Complex forward FFT (radix 4).
DSP_vecsumsq:
Sum of squares.
DSP_w_vec:
Weighted vector sum.
E
evaluation module (EVM):
Board and software tools that allow the user to
evaluate a specific device.
external interrupt:
A hardware interrupt triggered by a specific value on a
pin.
external memory interface (EMIF):
Microprocessor hardware that is used
to read to and write from off-chip memory.
F
fast Fourier transform (FFT):
An efficient method of computing the discrete
Fourier transform algorithm, which transforms functions between the
time domain and the frequency domain.
fetch packet:
A contiguous 8-word series of instructions fetched by the CPU
and aligned on an 8-word boundary.
FFT:
See fast fourier transform.
flag:
A binary status indicator whose state indicates whether a particular
condition has occurred or is in effect.
frame:
An 8-word space in the cache RAMs. Each fetch packet in the cache
resides in only one frame. A cache update loads a frame with the
requested fetch packet. The cache contains 512 frames.
G
global interrupt enable bit (GIE):
A bit in the control status register (CSR)
that is used to enable or disable maskable interrupts.
