Description
The 21264 is the third-generation 64-Bit Alpha Microprocessor. It includes the latest
Alpha architecture extensions, such as Motion-Video Instructions and Byte/Word operations.
The 21264 completely controls its L2 cache and
provides flexible bus timing to support a range of L2 cache memory devices such as:
- 200MHz late-write SRAMs (3.2 GB/s)
- 166MHz (333MHz data rate) dual-data
clock-forwarded SRAMs (5+ GB/s)
- L1 Cache: 2 64bit datapaths with 3 cycle
load-to-use latency providing an 8+ GB/s Sustained Bandwidth
- L2 Bcache: 128bit datapath with 12 cycle
load-to-use latency providing a 3.2 GB/s Sustained Bandwidth
- System Bus: 64bit datapath with 80 cycle
load-to-use latency providing a 1.6 GB/s Sustained Bandwidth
