Cache Memory

'Cache memory' tih hi i phone-ah leh computer-ah te i lo hmu fo tawh ngai em?

Computer lam subject la phei chuan Operating System kan zir chuan, Cache memory hi kan hmelhriat furin ka ring. Amaherawhchu, a awmzia leh a țangkaina hre lo kan tam ve leh thei tlat.

Eng nge Cache memory?

• Cache memory chu memory chi khat, size te tak te tihna a ni.
• Cache memory chu RAM leh CPU (Processor) inkara awm a ni a; tunlaiah chuan Hard disk leh Graphic card lam pawhin an nei fur tawh.
• CPU-in chak leh rang zual zawka hna a thawh theih na’n leh rang zawka a hnathawh turho RAM atanga a lak theih na’n a an siam a ni.
• Cache memory hi memory chi khat, speed sang tak a ni.
• Cache memory-ah hian file leh data a in-store ve ngai lo va, link emaw, reference emaw hi a list in a awm țhin.
• Cache memory hi user tan hmuh theihin a awm ngai lo.
• Heng list ațang te hian CPU chuan a hnathawh tur list-te chu awlsam takin cache memory atangin reference chu a la țhin a. CPU-in RAM chhunga a hnathawh tur chu zawn buai ngai tawh lo vin, a bul lawka cache memory atangin rang takin a la zung zung thei tawh a ni. (Mapping). Entir na’n: In sakna-ah Mistiri-in a bungrua leh a hmanrua leh a mamawh thil dangte chu bungraw dahkhawmna hmuna va zawn buai zel ngai tawh lo vin, a helper in a lo pe zung zung thin. A hna pawh a awlsam phah a, a rang zawk bawk a ni. Helper hi Mistiri hian a tih tur list a lo pe zel a, list-te chu helper-in a lo kawl reng a, Mistiri chuan a helper kut atang chuan a mamawh chu awlsam takin a la thei ta a ni. Mistiri hi CPU a ni a; Helper hi Cache a ni ve leh a; bungraw dahkhawmna hmun hi RAM a ni tihna a nih chu.

      

Cache memory chi hrang hrangte:-

1. Level 1 (L1) cache: Processor hnaih ber a ni a, processor chip-ah an bel tel țhin. A chak em em a; a te em em thung.
2. Level 2 (L2) cache: L1 cache aiin a capacity a lian hret a, Processor chip bul hnaiah tho an dah țhin. CPU nen hian High-speed alternative system bus hmangin an inthlunzawm țhin a; a chak em em bawk.
3. Level 3 (L3) cache: L1 leh L2 cache performance hmasawnna tura special taka duan a ni a. A memory tak hi chu, L1 leh L2 cache aiin a chak lo hret a, mahse, RAM speed a tihsan phah ve leh thung a ni. CPU core pakhat aia tam nei hovah chuan, core tinte hian anmahni țheuhvin L1 emaw, L2 cache emaw hi an chang țhin a; L3 cache erawh chu core tinte hian an ințawm țhin a ni.
