IBM’s new z196 microprocessor integrates four cores with 1.4 billion transistors fabricated in 45-nm technology on an area of 512 square millimetres. Operating at 5.2 GHz, the processor features a superscalar CISC architecture with an out-of-order pipeline.

Each of the four cores has a dedicated 64-KB L1 instruction cache and 128-KB L1 data cache, as well as a 1.5-MB L2 cache. The chip also integrates a shared 24-MB L3 cache in eDRAM technology. Each processor core consists of six RISC-type execution units, two of which handle integer processing, along with two load/store units, a binary floating point processor, and an explicit decimal floating point processor.

The z196 processor is designed to support symmetrical multiprocessing (SMP), and several processors are combined in a multi-chip module (MCM) with extremely high processing power. This module also includes two storage controller (SC) units with an additional 192 MB of off-die L4 cache, which support data rates up to 48 GB/s. The SC chip has 1.5 billion transistors and nearly the same area as the z195 chip.

Each MCM contains six z195 processors and two SCs with a total cache size of 376.5 MB (L1

The new P95020 power management IC from Integrated Device Technology is a system-on-chip device intended to be used in portable consumer products such as smartphones, portable navigation devices, mobile Internet devices and e-books.

According to IDT, the P95020 PMIC is the first of its kind to include a full set of system power regulation and management functions along with human interface subsystems, including audio and touch interfaces support. The embedded MCU is complemented by integrated peripheral subsystems including several switch-mode DC/DC converters and low-dropout voltage regulators, battery charge management, LED drivers, low-power stereo audio and voice codecs with mixer capability, a class D amplifier and headphone driver, a PLL for on-chip and external clock generation, and a touch screen controller. The MCU uses on-board system management resources, such as instrumentation SAR 12-bit ADC and a real-time clock, to provide optimum flexibility while reducing overall system power dissipation.

The embedded microcontroller of the IDT P95020 adds full programmability and flexibility to designs based on leading multimedia application processors. All functional blocks can be accessed over an I2C bus. The programmable voltage regulators meet the dynamic voltage adjustment requirements of application processors.
