Digital Signal Processors (DSP)
cache flush
Semiconductors; Digital Signal Processors (DSP)
A master processor (MP) operation that updates external memory by writing modified (dirty) data-cache subblocks back to memory, thus resetting that subblock’s present and dirty bits to 0.
trigraph sequence
Semiconductors; Digital Signal Processors (DSP)
A three-character sequence that has a meaning as defined by the ISO 646-1983 Invariant Code Set. These characters cannot be represented in the C character set and are expanded to one character. For ...
long immediate
Semiconductors; Digital Signal Processors (DSP)
On the master processor (MP), a 32-bit value that is either a signed or unsigned integer, a single-precision floating-point constant, a relative branch word offset, or an absolute address. The MP ...
packed halfwords
Semiconductors; Digital Signal Processors (DSP)
Two halfwords contained in a 32-bit word. The individual bytes within a word of packed halfwords are often operated on in parallel using multiple-halfword arithmetic.
symbol
Semiconductors; Digital Signal Processors (DSP)
1) A programmer-defined letter, numeral, sign, or other mark that represents the location of a particular datum item, instruction, routine, value, or address. 2) A string of alphanumeric characters ...
vector dot product
Semiconductors; Digital Signal Processors (DSP)
A mathematical term applied to the sum of the products of individual elements from two different vectors a and b.
convolution
Semiconductors; Digital Signal Processors (DSP)
A time domain reference for digital filtering that makes extensive use of sum-of-products.
