Toshiba Develops High Performance Microprocessor

Core

-‘MeP-h1’is the World’s First 1GHz Configurable Processor-

Toshiba Corporation has announced that it has developed a new

high-end processor core, MeP-h1, the first configurable

microprocessor to achieve a 1GHz clock speed. The MeP-h1 is

based on Toshiba’s “Media embedded Processor” (MeP)

architecture for digital consumer and other high performance

SoCs. It gives designers the flexibility to customize processors at

the design stage, including the ability to change processor

configurations and add custom instructions to satisfy application

requirements.

The performance of the new core was boosted by increasing the

number of instruction execution pipeline stages to nine, from five in

Toshiba’s previous processor core. The new core is also optimized

for design of high-performance customized processors by

integration of a reorder buffer circuit that manages and shortens

waiting cycles for user extension instructions. The present

implementation of the core was manufactured with 65nanometer

(nm) process technology, and that too contributed to achieving the

1GHz clock speed. The new configurable processor core is

designed with register transfer level description (RTL) and can be

manufactured with other process technology, including 90nm

technology.

Development background:

The market for digital equipment supporting images, audio and

communications is growing fast. However, the required

performance and type of data processing in system LSI differs by

application, and the overall volume of handled data is rapidly

increasing. As a result, there is growing demand for customizable

high-performance embedded processors. Toshiba will continue to

develop MeP technology and to apply high-end gigahertz-level

MeP cores to SoC for digital products.

Outline of MeP:

MeP is a configurable processor that allows designers to

customize processor configurations, including custom instructions

and embedded memory capacity, in about 1 million different

combinations. The processor features small chip size, low power

consumption and high-speed processing. It is based on a 32-bit

RISC processor, appropriate for digital media products that require

processing of large volume of image and audio data, such as

digital TVs and DVD recorders.

MeP main features:

1. High-speed media processing (image and audio)

2. Customizable configuration, including embedded-memory

capacity

3. Extensibility of hardware allowing easy addition of functions

These features contribute to shorter development times for SoC

that integrate complicated functions, reducing the development

time for digital products.

Toshiba uses MeP in its own products and also licenses the

technology to third parties that require flexibility in circuit design.

Users who want to apply MeP to their own products can download

MeP design data and related information from Toshiba’s dedicated

website, http://www.MePcore.com/, after registration and

completing a license agreement.

Roadmap of MeP:

Toshiba developed its first MeP core, MeP-c1 which had a 5-stage

pipeline structure in 2001. Toshiba expanded MeP functionality,

creating its line of c-series products, with the MeP-c2 and MeP-c3.

The new core announced today, MeP-h1, introduces a 9-stage

pipeline structure as the first core in the new high-performance h

series. Toshiba is also developing MeP-c4, an enhanced c-series

core
