Digital Signal Processors (DSP)
Pending interrupt
Semiconductors; Digital Signal Processors (DSP)
A maskable interrupt that has been successfully requested but is awaiting acknowledgement by the CPU.
Spinning
Semiconductors; Digital Signal Processors (DSP)
A technique for continuous monitoring of a status flag in a register or memory location in which the processor repeatedly polls the flag until the awaited status change occurs.
Multiple-byte arithmetic
Semiconductors; Digital Signal Processors (DSP)
Multiple arithmetic with ASize set to byte. The arithmetic logic unit (ALU) acts like four parallel byte ALUs because the carry-path is broken between bits 24 and 23, bits 16 and 15, and bits 8 and ...
IEEE 1149.1 standard
Semiconductors; Digital Signal Processors (DSP)
“IEEE Standard Test Access Port and Boundary- Scan Architecture”, first released in 1990. See also JTAG.
Fast mode
Semiconductors; Digital Signal Processors (DSP)
A master processor (MP) floating-point unit mode in which MP floating-point instructions are executed with all denormals treated as 0 for both input operands and the output result.
Pulse code modulation (PCM)
Semiconductors; Digital Signal Processors (DSP)
A technique for digitising speech by sampling the sound waves and converting each sample into a binary number.
Reserved (R)
Semiconductors; Digital Signal Processors (DSP)
A term used for a bit-, byte-, field-, or coded-value that is set aside for future small computer system interface (SCSI) standardization.
