Processor (CPU) IP Cores Overview

In the semiconductor industry, an IP core is a building block that has been developed by a company and is sellable.  In todays SoC designs, many IP blocks are used. The most common one is a processor (CPU) IP core. In this article we will describe the processor IP cores in the market and provide information regarding the selection process.

 

Selecting a Processor IP

 

There are a number of different factors that should be taken into consideration when assessing a CPU IP. This criteria includes elements such as CPU performance, power consumption, memory, supporting peripherals, industry requirements, and overall costs. Performance, power consumption, and functionality of the core should be the primary parameters that guide your final decision.

 

Performance

The most important parameter to judge a CPU system is its performance. You want the processor to be fast enough to fulfil your requirements. A good way to select a CPU is to shortlist a few options and run trial simulations with your code to formulate your own benchmarks.

 

Memory

You will have to go for a processor  IP that is able to support the entirety of your software program and the additional data memory. Remember: most microcontrollers have a limited amount of address space, which is why you need to search for a solution that can accommodate your program.

 

Power

Keep in mind that if you are investing in a processor with great performance, it is also going to increase the power consumption. If you look around, you will be able to find solutions that offer high performance with low power consumption.

 

Peripherals

The supporting peripherals that accompany your CPU are just as important as the unit itself. Since you are paying an additional cost for them, you will want to maximize their potential. Ideally, you will want to go with a processor whose peripherals overlap with the technology your application requires for execution. This results in cost savings, which is a welcome bonus.

 

Size & Costs

The costs associated with a CPU IP are very important to take into consideration. These are both costs related to the core size (=silicon size) Not only should the price of the core itself fall within your budget, but you also need to think about the training costs, supporting development tools, and peripherals you will need to maximize the use of the processor. Make sure to check all the cost associate with the core such as silicon size, and royalties.
