![]() Increasingly, the designers of high performance sys- tems, including PC and RISC based computers and high speed telecommunications applications, rely on synchronous SRAMs to design caches that provide data at the speeds they require. IDT: IDT71V124SA12Y : 3.3V CMOS Static RAM 1 Meg (128K x 8-Bit) Center Power & Ground Pinout 3.3V CMOSRAM 1 128K ×8. Data stored by the processor in the L2 cache is periodically off-loaded to the DRAM (extended or Level 3 memory) or to one of the disk drives. : : IDT: IDT71V124SA12Y : 3.3V CMOS Static RAM 1 Meg (128K x 8-Bit) Center Power & Ground Pinout 3.3V CMOSRAM 1 128K ×8 8. The L2 cache resides on the board with the processor or on SIMMs (Single In-Line Mem- ory Modules) that are located near the proces- sor. In workstations, the L2 cache may be required to operate at processor speed. In PC applica- tions, the L2 cache runs at one half to one third of the processor speed. It is many times larger than the L1 cache and is usually designed so that 90% of the time, the processor can find the data it needs there. Optim ize t he amo unt of time r equire d to p rovid e data to the CPU when there is a miss on L1.Called the Level 1 or L1 cache, this small mem- ory is found on the microprocessor chip and runs at processor speed. ![]() Store the ins tructi ons and d ata f or the p roces sor.In many computer systems, whether a PC, a RISC workstation, or a mainframe, caches are used to: A cache is memory used to temporarily store data.
