META HTP IP CORE

Imagination Technologies' META™ HTP processor core is a low-power unified CPU/DSP processor based on a multi-threaded architecture that enables developers to use a single core to replace multiple CPU and DSP cores. A four threaded META HTP delivers up to 1610 DMIPS in a 65nm process.

Traditional processors are often stalled due to multicycle memory latencies, or unproductive whilst performing context switches in software under control of a multitasking RTOS. META HTP supports multiple threads in hardware, each a virtual processor operating in a parallel/overlapped manner with no context switching overheads. On each cycle one or more threads will execute depending upon the resource required by each thread, maximising central ALU and memory utilization - superthreading allowing threads to run simultaneously provided they are not competing for the same resources.
