Microprocessor evolution
One of the particularly interesting aspects of microprocessor evolution is
the way that many microprocessor cores are now finding their way into true
system on chip (SoC) implementations. These implementations are
particularly prevalent in applications such as integrated digital television (iDTV)
where a true SoC can deliver significant cost savings across a high volume
production run of TVs, set-top boxes or digital TV recorders (DTRs).
In many SoC implementations the microprocessor core will be just one of a
number of cores in the IC, all of which are tasked with specific functions.
In the case of Toshiba’s latest SoCs for iDTV and DTR, a 64-bit RISC microprocessor core is combined with Media embedded
Processor (MeP) modules that free the host processor from compute-intensive
graphics and multimedia processing tasks.
