MC8641DVU1500KE

MC8641DVU1500KE Description

The MC8641DVU1500KE uses two high-performance superscalar e600 cores running at up to 1.5 GHz. This three-issue machine has a compact 7-stage pipeline which is particularly efficient with code that branches unpredictably. It avoids the extensive delays associated with flushing a long pipeline on mispredicted branches. Unpredictable branching is typical of code paths driven by the largely random arrival of different types of packets. The MC8641DVU1500KE supports up to 8 out-of-order instructions on the system bus that allows for making forward progress even while waiting for previous instructions to finish (ie, access to main memory required). The e600 has an onboard 128-bit vector processor for efficient data movement (useful for copying TCP payloads from kernel space to user space) and for math functions that rival a DSP.
