Alpha Microprocessor - Samsung System LSI

The 21164 Alpha microprocessor (referred to as the 21164) is a high-performance implementation designed for Windows NT desktop PCs and workstations. The 21164 has a superscalar design capable of issuing four instructions every clock cycle. The integration of an instruction cache, data cache, and second-level cache unrivaled microprocessor performance. The 21164 uses a high-performance interface to access main memory, data buses, and an optional board-level cache.

21164 Microarchitecture

The 21164 consists of five independent functional units: the insruction fetch, decode, and branch unit; the integer execution unit; the memory-management unit; the cahe control and bus interface unit; and the floating-point uint. There are three on-chip caches: the instruction cache, the data cache, and the second-level cache.

Thermal Management

The 21164 dissipates approximately 43W at 500 MHz. Conventional forced air cooling methods are sufficient to remove heat and maintain the highest levels of reliability. The user may also define an application-specific heat sink.
