For both the systems, size of L1 Cache is -
L1 Cache - 256-bit data path, Full Speed
L1 Data Cache - 32 KB data cache, Integrated
L1 Instruction Cache - 32 KB instruction cache, Integrated
L1, "Level1" orprimary cache, is used for temporary storage of instructions and data organised in blocks of 32 bytes. Because it's built in to the chip with a zero wait-state (delay) interface to the processor's execution unit, it is limited in size.
Itkeeps most frequently used instructions with L2 holding the next most likely needed bits of data.
