UltraSPARC-I 143MHz was a 64-bit SPARC microprocessor designed and introduced by Sun Microsystems in late 1995.

Cache[edit]

Main article: UltraSPARC-I § Cache

In addition to the on-chip cache, this chip also required an external cache that is either 512 KiB, 1 MiB, 2 MiB, or 4 MiB with a line size of 64 bytes.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
