HEADLINE: Java native micro for Internet applications

Java applications including Internet-enabled cellphones, video phones, network computers and set-top boxes are now
supported by a Java native microprocessor family from Patriot Scientific Corporation.

Known as the PSC1000 family, these devices will run at 100MHz and can be supplied in 5 and 3.3V versions. They include a
separate I/O processor to off-load timing and data transfer
responsibilities, and feature an interrupt controller, a direct memory
access controller and a programmable memory controller. The memory
controller can control DRAM, VRAM, flash, SRAM and EDO DRAM, while all memory timing and strobes can be programmed to
1/4 clock cycle to maximise the memory performance.

The I/O processor can be used to generate video; refresh an LCD;
transfer CD quality audio data; transfer data to and from
an intelligent network controller; time ignition and fuel injects;
control motors using pulse width modulation; and much more.

It is a programmable multi-function peripheral that can be programmed to handle a variety of tasks traditionally handled by external hardware.

HEADLINE: Java micro aimed at the Internet market

Thame Components has introduced a 0.5m version of the Patriot Scientific Corporation Java native microprocessor family
aimed at the Internet market.

Known as the PSC1000 family, the devices will run at up to 100MHz and can be supplied in 5 and 3.3V versions. They
incorporate a separate I/O processor to off-load timing and data
transfer responsibilities, which can be used to generate video,
refresh a LCD, transfer CD quality audio data, transfer data to and from
intelligent network controllers and control motors
using pulse width modulation.

Several other peripherals are also incorporated including an interrupt
controller, direct memory acccess controller and a programmable memory controller. This memory controller can control DRAM,
VRAM, flash, SRAM and EDO DRAM with its glueless bus interface and all memory timing. Strobes can be programmed to 0.25 clock cycle to maximise the memory performance.

The PSC1000 processors will run Java 'natively' rather than the
interpreted mode.
