Cypress CY7C601-25GC – First package with heatspreader – Omitted on later versions
In Mid-1987 Sun Microsystems (now owned by Oracle) released the SPARC (Scalable Processor ARChitecture) processor architecture to be used in their computers (replacing the 68k based systems they had previously used). The SPARC was designed from the outset to be an open architecture, allowing manufactures to license and built processors that implemented it using whatever technology they wished. The goal of this was to 1) build a large SPARC ecosystem and 2) keep prices in check by fostering competition among manufacturers. The SPARC is still used today by Oracle, Fujitsu, the European Space Agency and others, owing largely to its design as an open architecture from the very beginning.
The first version was made by Fujitsu on a 20,000 gate array at 1.2 micron and ran at 16.6MHz. In July 1988 Cypress (later to be spun off as Ross and make the famous HyperSPARC line) announced the CY7C601. This was the fastest implementation of the SPARC at the time. It was made on 0.8u CMOS process and contained 165,000 transistors, dissipating around 3.3Watts. As was typical of many processor designs of the time, it was an integer only processor, requiring a separate chip (the CY7C602) for floating point work. In September of 1988, Cypress cross licensed the ’601 to Texas Intruments in exchange for rights to the 8847 floating point processor. This was mainly to appease one of Cypress main customers who demanded that a second source for the ’601 chips be available, a demand more common in the 1970s then in 1988 but Cypress obliged. Cyrpress also gained the rights to make the next generation SPARC processor that TI was developing. TI would go on to make many SPARC processors, and continued to be the primary fab for Sun up through the SPARC T2 Plus in 2008. Oracle now used TSMC to fab the T3 and T4 SPARC processors.

The last week has been filled with new processor announcements, mainly for phones, but cameras as well. (yes they run some powerful processors now too).
TI is barely shipping products with its dual-core OMAP 4 applications processor and has already announced its successor, the OMAP 5. The OMAP 5 will be a 2GHz dual core ARM Cortex-A15 (the next ARM generation after the A9). It also includes a pair of ARM Cortex-M4 processor. the Cortex-M4 is a 150-300MHz microcontroller oriented processor. This will allow the OMAP 5 to run basic background tasks on the slower (lower power) cores while reserving the high power cores for tasks that actually need them, increasing battery life.
Broadcom continues its drive to enter the smart phone business with the BCM28150, a 1.1GHz dual core ARM Cortex-A9 compatible with Google Android. In December they released the BCM2157, a 500MHz dual core ARM11 processor for low-end smart phones
Samsung decided to rename the Orion processor (announced back in November) to the Exynos 4210. A bit of a mouthful compared to Orion.
Qualcomm showed off the APQ8060 in HP’s new TouchPad. This is a dual core version Snapdragon processor we have become very familiar with. Qualcomm has an architecture license from ARM so they are free to design their own cores without having to stick to ARMs own implementations (such as Cortex-A9 etc). This gives Qualcomm more flexibility to design in features they need, and tweak design more best efficiency.
Smart phones aren’t the only ones getting new processors. Digital cameras now require immense amount of processing power (especially to handle 1080p video recording. Fujitsu (yah, they still make a lot of processors) announced the Milbeaut MB91696AM. This is a dual core ARM processor with many other DSP functions capable of handling 14Mpixel shooting at 8fps, as well as full HD video.

TI has purchased Luminary Micro for an undisclosed amount of money. TI, one of the larger producers of embedded processors, and applications processors for mobile phones add significantly to their portfolio by adding Luminary, maker of ARM Cortex based microcontrollers. Most of TI’s line of processor are now ARM based. They do of course also make MCS-51 products as well as their VERY widely used DSP series (such as the TMS320 series).

When you think of multi-core CPU’s what comes to mind? Intel? AMD? Perhaps Nvidia, but certainly not TI.
Alas though, the embedded CPU/MCU market is by far the largest user of multicore CPU’s. Many systems controllers have an ARM main core, and then a MCS-51 core for IO stuff, or another ARM core. The iPhone has no less then 3 ARM cores in it.
TI just released the MSP430FE42X2, in large quantities its a mere $1 US. It includes 2 complete MSP430 cores, along with an LCD driver, and 32K of Flash. Where will you find it? Its marketed as a complete power meter solution, only other component needed to measure your houses power draw is a voltage regulator.

Today I got a not so old (2006) Infocus IN24 projector. It had bit the dust due to corrosion from the warm salty air in Maui.
What did I find inside? besides some amazingly cool optics, and power components, there was a large TI DLP Processor, specifically the DDP2000, a rather large BGA chip, that integrates most of the projectors functions as well as a DSP core, and a ARM 946 CPU core. running at 120MHz, good enough for 800×600 resolution.
Processor is the one marked DLP, bare die is a SRAM, far right is the DLP mirror, imaging chip (just layed on the board for your viewing)
