META HTP IP Core

The META™ HTP 32-bit processor core is a latency-tolerant SoC application processor with a rich DSP feature set, based on a multi-threaded architecture. It enables developers to replace multiple processors and DSP cores with a single unified core. A four-threaded META HTP delivers a true 2.4 DMIPS/MHz.

Traditional processors are often stalled due to multi-cycle memory latencies, or unproductive while performing context switches in software under control of a multitasking RTOS. META HTP supports multiple threads in hardware, each a virtual processor operating in parallel with no context switching overheads. One or more threads execute on each cycle depending upon the resource required by each thread, maximizing central ALU and memory utilization. Superthreading enables threads to run simultaneously provided they are not competing for the same resources.
