Imagination Meta

From Handwiki

The META is a 32-bit multithreaded microprocessor developed by Metagence Technologies Division from Imagination Technologies.[1] First version of META were developed in 2001 as META-1 multithreaded DSP core aimed for audio, radio and video processing.[2] META HTP core family was announced in 2007 and is based on META-2 architecture.[3][4] META family consists of Meta HTP applications processors (400–700 MHz on 65L – 65G process[3]), META MTP Embedded Processors and Meta LTP Embedded Microcontrollers.[5]

It is supported by the Linux kernel as of version 3.9.[6][7][8]

In 2018 March, LWN.net reported that Imagination Technologies redirected its focus away from Meta after its purchase of MIPS Technologies in 2012. This has led to a proposal on Linux development mailing lists to remove support for the architecture from the kernel which became effective with the release of Linux 4.17 in June 2018.[9][10]
