24-BIT DIGITAL SIGNAL PROCESSOR

Motorola DSP56307, membala wa banja la DSP56300 la ma programmable digital signal processors (DSPs), imathandizira mapulogalamu opangira ma waya opanda zingwe ndi ntchito zosefera.The on-chip enhanced filter coprocessor (EFCOP) imayendetsa ma aligorivimu osefera mogwirizana ndi ntchito yayikulu, motero imakulitsa magwiridwe antchito a DSP onse.Monga mamembala ena am'banjamo, DSP56307 imagwiritsa ntchito injini yothamanga kwambiri, ya wotchi imodzi-pa malangizo (code-yogwirizana ndi Motorolas yotchuka ya DSP56000 core family), chosinthira migolo, 24-bit adilesi, cache ya malangizo, ndi wowongolera wolowera kukumbukira mwachindunji, monga momwe zilili Chithunzi 1. DSP56307 imapereka magwiridwe antchito pa malangizo a 100 miliyoni (MIPS) pamphindikati pogwiritsa ntchito wotchi yamkati ya 100 MHz yokhala ndi 2.5 volt core ndi mphamvu yodziyimira ya 3.3 volt / zotulutsa.

Mwachidule
Pogwiritsa ntchito kamangidwe ka m'badwo wachiwiri wa ASMBL (Advanced Silicon Modular Block), XC5VLX330T-3FFG1738I ili ndi nsanja zisanu zosiyana (mabanja ang'onoang'ono), chisankho chomwe chimaperekedwa ndi banja lililonse la FPGA.Pulatifomu iliyonse imakhala ndi mawonekedwe osiyanasiyana kuti athe kuthana ndi zosowa zamitundu yosiyanasiyana yamalingaliro apamwamba.Kuphatikiza pa nsalu zapamwamba kwambiri, zowoneka bwino kwambiri, XC5VLX330T-3FFG1738I FPGAs ili ndi midadada yambiri yolimba ya IP, kuphatikiza ma 36-Kbit block RAM/FIFOs, magawo achiwiri 25 x 18 DSP, Sankhani ukadaulo wa IO wokhala ndi- mu impedance yoyendetsedwa ndi digito, Chip Sync source-synchronous interface blocks, system monitor performance,

MAWONEKEDWE
Mawonekedwe apamwamba a DSP56300 Core
● Malangizo 100 miliyoni pamphindikati (MIPS) okhala ndi wotchi ya 100 MHz pa 2.5 V core ndi 3.3 VI/O
● Khodi yachinthu yogwirizana ndi maziko a DSP56000
● Malangizo ogwirizana kwambiri
● Data arithmetic logic unit (ALU)
- Mapaipi athunthu a 24 x 24-bit parallel multiplier-accumulator
- 56-bit parallel barrel shifter (kusuntha kwachangu ndi kukhazikika; kutulutsa pang'ono ndi kugawa)
- Malangizo a ALU ovomerezeka
- 24-bit kapena 16-bit masamu thandizo pansi pa mapulogalamu
● Program control unit (PCU)
- Thandizo lodziyimira pawokha (PIC).
- Njira zoyankhulirana zokongoletsedwa ndi mapulogalamu a DSP (kuphatikiza zosintha zaposachedwa)
- Wowongolera pa cache wa malangizo pa-chip
- Pa-chip memory-chowonjezera cha hardware
- Nested hardware DO malupu
- Zosokoneza zobwera mwachangu zokha
● Direct memory access (DMA)
- Njira zisanu ndi imodzi za DMA zothandizira kulowa mkati ndi kunja
- Kusamutsidwa kumodzi, ziwiri, ndi katatu (kuphatikiza kusungitsa kozungulira)
- Kutha kwa block-kusokoneza kumasokoneza
- Kuyambitsa mizere yosokoneza ndi zotumphukira zonse
● Phase-locked loop (PLL)
- Imalola kusintha kwa mphamvu yotsika yogawa mphamvu (DF) popanda kutayika kwa loko
- Wotchi yotulutsa ndikuchotsa skew
● Thandizo la hardware debugging
- On-Chip Emulation (Pa CE) gawo
- Gulu loyeserera loyeserera (JTAG) doko lofikira (TAP)
- Njira yotsatsira adilesi ikuwonetsa kulowa kwa Pulogalamu ya RAM padoko lakunja
