24-BIT DIGITAL PONTS'O TS'OANA

Motorola DSP56307, setho sa lelapa la DSP56300 la li-programmable digital signal processors (DSPs), e ts'ehetsa lits'ebetso tsa meaho e se nang mohala ka ts'ebetso ea ho sefa ka kakaretso.The on-chip enhanced filter coprocessor (EFCOP) e sebetsana le li-algorithms tsa filthara ka ho tsamaisana le ts'ebetso ea mantlha, ka hona e eketsa ts'ebetso le ts'ebetso ea DSP ka kakaretso.Joalo ka litho tse ling tsa lelapa, DSP56307 e sebelisa enjine e sebetsang hantle haholo, ea nako e le 'ngoe ea potoloho-ka-taelo (khoutu e tsamaisanang le Motorolas e tsebahalang ea DSP56000 core family), barrel shifter, 24-bit addressing, cache ea litaelo, le taolo e tobileng ea ho fihlella mohopolo, joalo ka Setšoantšo sa 1. DSP56307 e fana ka ts'ebetso ho litaelo tse limilione tse 100 (MIPS) ka motsotsoana ho sebelisa oache ea ka hare ea 100 MHz e nang le 2.5 volt core le matla a ikemetseng a 3.3 volt.

● Litaelo tse limilione tse 100 motsotsoana (MIPS) ka oache ea 100 MHz ho 2.5 V core le 3.3 VI/O
● Khoutu ea ntho e tsamaellana le DSP56000 core
● Sehlopha sa litaelo tse bapang haholo
● Data arithmetic logic unit (ALU)
- Sekokelli sa liphaephe tse tsamaeang ka botlalo tsa 24 x 24-bit parallel multiplier-accumulator
- 56-bit parallel barrel shifter (ho fetoha ka potlako le ho tloaeleha; tlhahiso ea molapo o fokolang le ho arola)
- Litaelo tsa maemo a ALU
- Ts'ehetso ea lipalo tsa 24-bit kapa 16-bit tlasa taolo ea software
● Sehlopha sa taolo ea lenaneo (PCU)
- Ts'ehetso ea khoutu e ikemetseng (PIC).
- Ho sebetsana le mekhoa e ntlafalitsoeng bakeng sa lits'ebetso tsa DSP (ho kenyeletsoa le li-offsets hanghang)
- Taolo ea cache ea litaelo tsa on-chip
- Setaki se atolosoang sa memori ea on-chip
- Nested hardware DO loops
- Litšitiso tsa ho khutlisa ka potlako
● Ho kena mohopolong ka kotloloho (DMA)
- Likanale tse tšeletseng tsa DMA tse tšehetsang phihlello ea kahare le kantle
- Phetisetso e le 'ngoe, tse peli, le tse tharo (ho kenyeletsoa le buffering e chitja)
- Qetello-ea-block-phetiso e sitisa
- Ho qala ho tloha meleng ea tšitiso le li-peripherals tsohle
● Phase-locked loop (PLL)
- E lumella phetoho ea "low power divide factor" (DF) ntle le tahlehelo ea senotlolo
- Oache e hlahisoang ka ho felisoa ha skew
● Tšehetso ea ho lokisa hardware
- On-Chip Emulation (Ka CE) mojule
- Sehlopha se kopaneng sa liteko (JTAG) koung ea phihlello ea liteko (TAP)
- Mokhoa oa ho batla aterese o bonts'a phihlello ea ka hare ea Lenaneo la RAM boema-kepeng ba kantle
