A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. [ 1 ] : 104–107 [ 2 ] DSPs are fabricated on metal–oxide–semiconductor (MOS) integrated circuit chips.
AMD TrueAudio is a kind of audio co-processor. Block diagram of HiFi Audio Engine DSP, which TrueAudio is based on. Shows the 56-bit wide MAC unit.. TrueAudio is AMD ' s application-specific integrated circuit (ASIC) intended to serve as dedicated co-processor for the calculations of computationally expensive advanced audio signal processing, such as convolution reverberation effects and 3D ...
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.
The CA20K1 chip is a slave processor which requires a host CPU to control it. The CA20K2 adds an embedded RISC processor which controls the audio part; this configuration safeguards against the audio latency of its PCI Express interface. 20K2 also has more I/O ports, a DDR SDRAM memory interface, and a built-in Universal Audio Architecture ...
According to 2012 estimation, Qualcomm shipped 1.2 billion DSP cores inside its system on a chip (SoCs) (average 2.3 DSP core per SoC) in 2011, and 1.5 billion cores were planned for 2012, making the QDSP6 the most shipped architecture of DSP [12] (CEVA had around 1 billion of DSP cores shipped in 2011 with 90% of IP-licensable DSP market [13]).
Being a Modified Harvard architecture processor, the 56k has three memory spaces+buses (and on-chip memory banks in some of the models): a program memory space/bus and two data memory space/bus. [7] The stack area is allocated in a separate address space, which is called "Stack Memory Space", [8] distinct from the main memory address space. [9]
